THOMSON, ELECTROTYPERS, PHILADA. PRESS OF WILLIAM J. DORNAN, PHILADA. PREFACE TO VOLUME II. On behalf of his fellow-collaborators the Editor takes this occasion to thank the surgeons and surgical teachers of America for the cordial reception so quickly extended to the first volume of the work, and to express the hope that the second and concluding volume may be simi- larly approved, both from the didactic and practical standpoints. If it be possible to judge from the written expressions already re- ceived from the most prominent teachers of Surgery, the work seems likely to fulfil one of its chief purposes—namely, the presentation of a thoroughly modern text-book reflecting the methods of teaching de- veloped by large experience. Practitioners of surgery, it is hoped, will find it equally suited to their needs, as every effort has been made to afford all necessary guid- ance in the principles as well as in every practical detail of surgical science and art. The illustrations, which are largely original, have been chosen with critical care, and each of the profuse series will be found to elucidate important matters and to supplement the text most valuably. It is no small task to gather a comprehensive and authoritative expression of. modern surgical knowledge. How far this effort has succeeded it remains for the surgical public to determine, but the Editor can at least say that he submits with confidence these volumes, * embodying as they do the most earnest work of the eminent gentle- men whose information is a credit and honor to the position of America in the surgical world. The Editor also wishes to renew here his ex- pressions of obligation to the gentlemen who have so kindly assisted him, as mentioned in the Preface to the First Volume. ROSWELL PARK.

INJURIES AND SURGICAL DISEASES OF THE HEAD. Roswell Park, M. D. The Scalp. Erysipelas and cellulitis of the scalp are the result of the same infections and conditions as when met with in other regions, but are peculiarly prone to occur here because of the liability to infection from the hair with the material concealed in and upon the surface. They lead frequently to suppuration, in which case abscesses form that may extend inside the cranium, as into the frontal or other sinuses. These are common about the orbit and in the upper eyelid, and unless speedily incised may lead to gangrene. Multiple abscesses are also common. Disturbances of sight and hearing as sequels of these infections are occasionally met with. The principal danger from these purulent col- lections pertains to intracranial infection or general sepsis, usually of pysemic type. Carbuncles are frequent upon the back of the neck, though they seldom occur upon the scalp proper. Even small ones are rarely met here. Nevertheless, car- buncles have been known to extend from one ear around to the other. Occurring in this region, the infection is serious and prognosis is unfavorable. Met with here, they should be treated, as elsewhere, by free incision, with extirpation of all infected tissues. Their presence should always excite the suspicion of diabetes, alcoholism, or pronounced uric-acid diathesis ; for each of which, when recognized, appropriate medication should be adopted. Gangrene' of the scalp may result either from infection or injury. In badly- nourished children it may follow various skin eruptions. That type known as gangrenous emphysema may also be met with here. All forms of gangrene may be followed by necrosis of the underlying skull, especially when the periosteum is involved. Threatening gangrene should be treated by early excision of the sus- picious area, or at least by incision to relieve tension. Actual gangrene should lead to prompt extirpation of all infected tissues. The various ulcerations of the scalp which may result from Avounds, phlegmons, carbuncles, etc., as well as from the infectious granulomata—i. e. syphilitic and tubercular—or those of cancerous nature, differ only from other ulcerations else- where by the accident or limitation of their location. The most common ulcera- tions of non-traumatic origin are due to breaking down of neoplasms. The treat- ment for each of these does not require special mention here, having been already described in the other parts of this Avork. Gaseous Tumors of the Scalp.—The most common of these is ordi- nary emphysema, which may result from injury to the upper air-passages 17 18 INJURIES AND SURGICAL DISEASES OF THE IIEAI). or even involving the lower. Thus, fractures of the nasal bones or of the base of the skull may permit the distention of the subcutaneous cellular tissue by forcible inspiration of air. Emphysema of the seal]) may be a valuable diagnostic feature in certain instances. When con- nected with a wound it would best be enlarged in order to permit the escape of contained air. Otherwise, these puffy swellings usually dis- appear spontaneously by absorption of air into the veins. In cases of malignant or gangrenous emphysema, early and numerous incisions should be made, after which antiseptic solutions, etc. should be gener- ously resorted to. Pneumatocele.—A pneumatocele is a chronic gaseous tumor, being a cavity distended with air which has escaped from the cells of the underlying bone, bounded on the outside by the seal]), beneath by the cranium. They are met with about the mastoid or the frontal region. Not more than two dozen cases in all are on record. In consistency these tumors are elastic, while the escape of air upon pressure is some- times to be heard upon auscultation. Their explanation is almost always a defect of the inner wall of the mastoid cells, through which air may be forced from the pharynx through the middle ear by violent effort. Bony defects which might permit this condition are met with in a small percentage of craniums. The best results in the way of treatment have been achieved by puncture, with the injection of weak iodine solution. Syphilis of the Scalp.—The seal]) may be the site of syphilitic eruptions, ulcerations, or necroses. These differ in no respect from similar lesions elsewhere. In syphilitic disease of the bones there is greater ease of infection and breaking-down of the overlying skin because of their proximity. Gumma of the soft parts or of bone, and caries of the latter, will nearly always lead to superficial ulceration, which shall call for a combination of local surgical and general medical treatment. Tuberculosis of the Scalp.—This same may be said of tubercular lesions, which when superficial will, for the most part, assume the lupoid type, or when deep will be inseparable from other manifestations of tuberculosis of the flat bones. Tumors of the Scalp.—These may be divided into the congenital and the acquired, as well as into the benign and malignant. Of the congenital tumors, the dermoids are of most interest. In order to fully understand dermoids of the cranium we must remember that originally the dura and the skin were in contact, and that the cranial bones develop as an after-thought. This will explain the occurrence of dermoids either beneath or outside of the bone or their simultaneous appearance and possible connection. Many of the so-called atheromatous cysts or wens are really of dermoid origin. Those which are extracranial need only antiseptic incision or excision. It will often be enough to split such a cyst with a bistoury, after which each half of the sac can probably be easily detached from the bed in which it has lain. Should intracranial con- nection bg discovered, the bone-chisel and sharp spoon will be necessarily called into employment. Some of these dermoids perforate into the orbit, and may have to be followed into that location. All of the dermoids and cysts of the skull may require to be differentiated from meningoceles and prolapsus cerebri: in fact, one should always distrust a con- genital tumor about these regions, but particularly those near the middle line. The external tumors never alter in size during sleep, and can rarely, if ever, be pressed back within the cavity of the skull; which cannot be said of either of the I)rsCASKS OF THE BLOOD-VESSELS. 19 other conditions just mentioned. In case of doubt the exploring needle may be used. Cornu cutaneum is seen more often upon the scalp than elsewhere, its explana- tion being afforded in the chapter on Tumors in Volume I. It calls for complete excision, which, if thorough, will be sufficient. Of- the other tumors, benign or malignant, most varieties may be met with in this region. Subcutaneous collections of fat are not so common, nor are fibromata. Various bony growths may be met with, while in certain cases the signs of brain-pressure are to be explained only by their extension within the cranium. Malignant tumors are common about the scalp and the cranium ; they assume, however, no conventional appearance, and may be met with in any shape or form, those of the scalp alone occurring either as carcinoma or epithelioma from its epithelial elements, or as sarcoma from its meso- blastic elements. Tumors primary in the periosteum or bone must neces- sarily be of sarcomatous nature, while those of the type which perforate to the surface may be either sarcoma or possibly endothelioma. With regard to the general character of these growths enough has been already said in Volume I. Concerning their extirpation (for there is no other treatment than this), operations of varying degrees of severity may be called for. The superficial epithelioma should be, if possible, attacked before it has become adherent, in which case everything should be removed down to the underlying periosteum, after which a plastic operation will permit the repair of the defect, so that primary union of the whole surface may be secured. Any malignant growth which is adherent to the underlying cranial bone calls not only for removal of its own substance, but for that of the bone to which it is attached. To fail in this is to invite recurrence. This may necessitate more or less extensive osteoplastic resections of the bone, but the condition permits of no middle course. Very extensive resections of bone have been made with success, and need not be abstained from unless there be good reason to fear involvement of the dura or cortex. In this case the advantages and dangers must be carefully weighed before proceeding to operation. During operations on the bone great care should be taken, especially in certain regions, to avoid injury to the intracranial sinuses, although we have learned that these may be ligated and intervening portions removed—almost with impunity when necessary. But the wounding of the sinus by the point of an instrument or spicule of bone may lead to a most hazardous and annoying complication, and is to be prevented when possible. A small wound in a sinus may be plugged with gauze, which may remain for two or three days. There is always a possibility of air-embolism (see Chapter II. Vol. I.) when the sinuses are opened, since their walls do not easily collapse. Hemorrhage from the soft parts may be almost entirely controlled by the use of an elastic tourniquet stretched around the skull. Oozing veins in the diploe or in the bone may often be secured by pressing the tables of the skull together with bone-forceps, while at other times an antiseptic wax can be forced into the interstices of the bone and hemorrhage thus be checked. In certain cases where it seems impracticable to slide flaps and cover defects, the desired end may be obtained by skin-grafts after Thiersch’s method. Diseases of the Blood-vessels. Aneurisms and vascular tumors, especially the latter, are met with about the scalp. The form of aneurism most common is the so-called cirsoid, already described in Chapter XXXII. Vol. I. Single aneur- isms are, however, occasionally seen. These are, when upon the surface, always accessible, and are best completely extirpated. Cirsoid aneur- isms, when not too large, may be radically attacked, or, if excessive iu 20 INJURIES AND SURGICAL DISEASES OF THE HEAD. size, may justify ligation of botli external (or even both common) caro- tids. The ordinary venous tumors, so-called mevi, etc., may either be excised or treated by electrolysis. Arterio-venous aneurisms, either external or connecting with the orbit or with an internal sinus, have been seen and described, but are so rare as not to warrant further men- tion here. Varicose conditions of the external veins are also occasion- ally seen. These may be due to mere weakness of venous walls, or may be the result of disease of the same or of obstruction to return circu- lation. A rare and specialized form of blood-tumor, met with only on or within the cranium, is the so-called hernial dilatation of the superior longitudinal sinus. It may present through openings in the bone; sometimes pressure upon it will cause vertigo and perhaps greater prominence of adjoining veins, even of the jugulars. Non-inflammatory Diseases and Congenital Conditions of the Skull. Incomplete formation of bone (aplasia cranii) is occasionally met with. The bone is a secondary formation in the skull, the dura and skin being originally in contact; consequently, this condition can be easily explained as a failure to develop bone where it is normally met with. These defects are most common in the frontal and temporal regions. The bone may fail also to develop to ordinary thickness, and may be Fig. 1. Craniotabes (rhachitis) (Bruns). found as thin as paper or ossifying only in certain directions. Super- numerary bones may also develop, apparently to take the place of those previously lacking. Aplasia may also be a unilateral defect, and con- tribute toward the formation of meningocele. Atrophy or anostosis— i. e. complete disappearance of cranial bones—is occasionally observed. It may be an interstitial or an eccentric process, and may happen at any DISEASES AND CONGENITAL CONDITIONS OF THE SKULL. 21 point or at several spots. Up to a certain extent it is the rule in the skulls of the aged, where the bones become reduced to the thinness of paper or may in certain places completely disappear. Senile atrophy, in Fig. 2. Leontiasis: skull of a Chinese woman (U. S. A. Museum, No. 10,620), other words, is a normal process, and is to be expected after the sixtieth year of life, its possibility being not forgotten when operations are under- taken upon the skulls of those advanced in years. Eccentric atrophy Fig. 3. Osteoma of skull (Mudd). may also occur from pressure of soft or hard tumors, among them the so-called Pacchionian bodies. It is stated also that increasing hydro- cephalus may produce an internal and eccentric anostosis. 22 INJURIES AND SURGICAL DISEASES OF THE HEAD. Craniotabes or Cranial Rickets.—It is particularly in the skull Fig. 4. Same, seen from below. that the manifestations of rickets are most common, the bone becoming) unduly thick and the general shape being changed. Usually there is Fig. o.

In spite of these changes, the bone often becomes affected by pressure to such an extent that a rachitic or hydrocephalic child, confined in bed and moving little or not at all, will develop a skull showing the effect of such pressure. Many rachitic skulls show areas of atrophic thinning, dispersed irregularly, while the inner surface may show the markings of the convolutions impressed upon it by the softness of the bone. Leontiasis.—This has been already alluded to in Chapter XXXV. Vol. I. It refers to an abnormal thickening confined entirely to the skull and the facial bones. The trouble begins usually in the latter, but later involves the former. By the distortion of nature’s purpose a most peculiar appearance is given to the face and head. The pathology of the disease is absolutely unknown : the influence, once operative, continues to act until the bone becomes enormously thick- ened, and patients die either of brain-pressure or of inanition, the latter caused by encroachment upon the natural cavities of the face and cra- nium to such an extent that swallowing becomes impossible. The con- dition is absolutely hopeless. Surgical Affections of the Cranial Bones. The acute affections of bones have been already dealt with at con- siderable length in Chapter XXXAT. Vol. I., and but little needs to be said here in addition to statements therein contained. Acute 'peri- ostitis is, for the most part, due either to syphilis or to an infection follow- ing injury. In the latter case it proceeds from the margin of the wound, and may spread to a considerable distance. It is in some instances secondary to deeper infection extending from the middle ear, and then is found posteriorly to the ear and externally to the mastoid cells. Con- genital openings or defects of the sutures about the mastoid seem to have much to do with the travelling of infectious lesions in these localities. Acute osteomyelitis is due to essentially the same causes as those just discussed. In this case it is especially in the diploe that the principal ravages are met with. Unless very promptly recognized and relieved by surgical measures, this is exceedingly likely to lead to sepsis of the pysemic type and at a relatively early period, the venous arrangement of the diploe favoring such type of disease. Chronicperiostitis, or pericranitis, assumes rather the ossifying type, and leads to a formation of new bone—at least when not of tubercular character. The chronic tubercular lesions, however, are practically all connected with the ravages of the granulation-tissue which always marks the presence of tubercular disease in bone, so that these affections assume the clinical form of caries of the skull. Cold abscesses are frequent in connection therewith. The tendency of the disease is nearly always to spread, and it should be checked as early as recognized. In other words, the bone-cliisel and the sharp spoon are in these cases nearly always called into play, the consequence being that the dura is often exposed before the lesion is eradicated. This need occasion no alarm, but should give rise rather to a feeling of satisfaction at the thoroughness with which the surgical attack has been carried out. Necrosis of the skull is ordinarily the result, directly or indirectly, of injury, in which cases it is usually of the acute form, a fragment which has been too much separated from its surroundings to live, giving evi- 24 INJURIES AN1) SURGICAL DISEASES OF THE HEAD. dence of early and easily recognizable death. This necrosis is, for the most part, confined to the external table. Necrosis of slow origin is due either to tuberculosis or syphilis, perhaps more often to the latter. Under a cold abscess of the scalp or subperiosteal abscess will often be found at least a small area of dead external table which needs complete removal. Necrosis has also been observed to follow severe burns of the scalp. In utero the head is surrounded by amniotic fluid and is well guarded against injury. Nevertheless, as the result of* penetrating wounds or of falls on the part of the mother such injuries do occasionally occur. Most of the cases of skull fracture reported as occurring before birtli have really occurred during delivery. Multiple fractures of the skull of either character have been observed. During the process of parturition there nearly always appears a tumor of the scalp in the new-born, commonly spoken of as the caput mccedaneum, at the point where pressure upon the head has been least. It usually disappears quickly after birth. It is due to a collection of Injuries to the Head Previous to and During Birth. Fig. 6. Fracture of right frontal bone in a new-born infant; fracture extending into orbit (Bruns) blood, partly an extravasation, as the result of compression or injury. It is composed also of (edematous soft tissues of the surface. If incised, blood-stained serum is poured out. When this fails to rapidly resorb during the first days of the infant’s existence, and especially if it fluctuate, it may be incised under antiseptic precautions and blood-clot be turned out or the necessary indication met in a judicious way. In rare cases it suppurates, by which is produced an acute abscess which naturally calls for prompt evacuation. A collection of fluid blood between the periosteum and the bone is known as the cephalhsematoma neonatorum, such a lesion occurring IMPORTANT POINTS IN SURGICAL ANATOMY OF THE SKULL. 25 on an average once in two hundred cases. It is met with most often over the fissures, and appears, at least in some eases, to be produced by the sliding of the bones. This collection also usually promptly disap- pears. In case of failure it may be aspirated or, if necessary, incised. Before resorting to any operative procedure it would be well to make a careful distinction between a possible meningocele or encephalocele as a congenital defect and cephalhsematoma as an accident of delivery. In the foetal head the cranial bones are easily displaced, and during delivery the size and shape of the head are materially altered, as must necessarily be the case in view of the tremendous pressure to which it is subjected in passing through the pelvis. It has been claimed that the dolichocephalic form of certain skulls is due to pressure exerted in the necessary direction during face presentation. Pre- mature alterations due to pressure may occasionally be met with, and may possi- bly give rise later to evidence of brain-pressure in the shape of epileptiform con- vulsions, etc. A depression in the skull of anew-born child which does not quickly right itself or yield to expanding influences from within should not be long allowed to go uncorrected, since disastrous lesions, for the most part of paralytic type, may result therefrom. In these days of aseptic surgery there is no reason why such operation as may be necessary to elevate a fragment or an entire bone should not be performed with full precaution. Important Points in the Surgical Anatomy of the Skull. It must be remembered, first of all, that the young and the aged have no dis- tinction of tables of the skull, but that the diploe which separates the two tables is an affair of middle age, develops slowly, and disappears after the same fashion— sometimes to such an extent as to leave the skull of almost paper-like thinness. In all operations, then, upon the young and the old, one must proceed with extreme caution, as expecting to find the skull quite thin. The lower limit of the squa- mous bone proper is the so-called masto-squamosal suture, and operations confined to the squamous plate alone are safe from injuring the sigmoid sinus on its inner side. The ridge at the posterior root of the zygoma indicates by its lower border the level of the mastoid antrum. A few lines above this, is the level of the base of the brain. The mastoid is present at birth and appears externally by the second year. Its antrum is present also at birth, though its air-cells do not develop until after puberty, their location being previously occupied by cancellous tissue. Most of these cells open into the antrum, a few directly into the tympanum. They are not always separated from the sigmoid sinus by bone. The partition between them is perforated by minute veins, forming an easy communication between the sinus and the antrum. Air escaping from the mastoid cells into the overlying tissue may cause emphysema from a basal fracture. In all operations upon the mastoid antrum one should keep to its outer side, and the higher and the more closely to the posterior zygomatic ridge he makes the first opening, the more sure is he to escape injuring the facial nerve. The groove for the sigmoid sinus extends to the jugular foramen from a point on the outside corresponding to the asterion. The lateral sinus may be indicated externally by a line from the superior border of the mastoid to the inion—i. e. from the asterion to the inion. The frontal sinuses are usually separated by a septum, which is often incom- plete or wanting. They are variable in size and outline, and do not develop until after the seventh year—in some cases to a relatively very large extent. The infundibulum, by which they empty into the nasal cavity, is often so small that when the lining membrane is involved it becomes closed, and retention with its accompanying symptoms—pain, tenderness, swelling, etc.—may ensue. Ulceration and erosion, however, may cause perforation internally to the supraorbital plates, so that pus may penetrate through the inner half of the orbit. Aside from its direct communication, the superior longitudinal sinus connects with the basal sinuses through the middle cerebral and the Sylvian veins, while 26 INJURIES AND SURGICAL DISEASES OF THE HEAD. communications with the middle meningeal veins are quite free. Where the frontal and diploetic veins enter the longitudinal sinus there are frequently dilatations in which inarasmic thrombosis often originates. This sinus is also connected with the veins of the nasal septum, so that a septic phlebitis may be directly propagated from the nose. So much of the lateral sinus as is contained in the sigmoid groove is known as the sigmoid sinus, which connects directly with the exterior through the mastoid and the posterior condyloid veins. In sinus thrombosis this mastoid vein is usually likewise affected. One or more condyloid veins accompany the hypoglossal nerve through the anterior condyloid foramen, and may also serve for the propagation of infection or exit of pus. While septic particles may be carried—usually through the internal jugular— from any part of the lateral or sigmoid sinuses, they may also be carried by way of the other veins above mentioned or the occipital sinus; all of which empty directly into the subclavian without passing through the internal jugular. These sinuses are all rigid tubes, always open, while the veins are thin and flexible, their calibre constantly varying with inspiration and expiration. The sinuses contain no valves, and these are very rare in the cerebral veins. So far as the lymphatics are concerned, there is free and easy communication between the internal and external plexuses and nodes. Into the superficial nodes, along the external jugular, outside of the deep fascia, empty all the external lym- phatics of the head. Intracranial infection shows itself in swelling of the deep cervicals beneath the deep fascia. Lymphatics are abuudant in the dura, and pathogenic organisms, once housed within the dura, And it easily open to invasion. The potential interval between the dura and the arachnoid is termed the sub- dural space, where considerable effusion may occur without marked symptoms, owing to its easy diffusion, while blood poured out here may travel even to the lowest parts of the spine and cause death by pressure upon remote points. The arachnoid bridges over the convolutions and does not extend into the sulci. It is not vascular; at certain points it is adherent to the pia, at others does not touch it. The subarachnoid space is formed in the latter way, and within it most of the cerebro-spinal fluid is contained. This space is unevenly distributed over the brain surface, most prominent beneath the posterior two-thirds of the brain, where there is a wide interval between the arachnoid and the pia, extending for- ward over the medulla and pons and as far forward as the optic nerves. This space connects with the ventricles by the foramen of Magendie, as well as with the sheaths of the cranial nerves. When these nerves escape from the brain or cord they are covered by all three membranes, the layers being most distinct along the optic nerves. Fluid injected into the subdural space may pass along the spinal nerves as far as the limbs. It is essential to realize this in order to appreciate how extensive is the surface exposed in leptomeningitis. Internal hydrocephalus is often the result of closure of the foramen of Magendie. The cerebro-spinal fluid is rapidly reproduced after traumatic escape. External hydrocephalus, or accumulation in the subarachnoid space, is a condition frequently due to tubercular infection. The pia is the vascular coat of the brain, supplied with an extensive network of fine nerve-fibres derived from the sympathetic and the cranial nerves, having intimate relations with the brain, to such an extent that leptomeningitis and encephalitis are almost inseparable. The nerve-supply to the cerebral membranes explains the severe pain of meningitis. Injuries to the Soft Parts of the Cranium. In direct connection with what has just been stated above, it is well to emphasize that the venous communications between the exterior and interior of the cranium are numerous, and that the frequency of these anastomoses explains the ease with which extracranial infections are propagated within ; in other words, these explain the frequency of septic mischief in the brain from external injuries. Penetrating- and incised wounds are frequent about the head, their prognosis per se, as well as their proper treatment, varying but little from that of such wounds in other parts, so long as the skull proper 27 INJURIES TO THE CRANIAL RONES. and its contents escape injury. Hemorrhage from scalp wounds may be free, even fatal. The most dangerous hemorrhages occur from the tem- poral vessels. Penetrating wounds are short, and the periosteum and underlying bone are usually also injured. Such small articles as blades of penknives, particles of dirt, etc. will often be found when the parts are carefully inspected, a measure never to be neglected. Contusions of the scalp and skull are spoken of as subcutaneous, subaponeurotic, or subperiosteal, and are most frequent in the frontal and lateral regions. Ecchymoses following them may be extensive and discoloration may spread over a large area. In traumatic haematomata resulting from various injuries incision should be early resorted to should blood-clot fail to resorb. Tkeatment.—In all head injuries the injured portion at least of the scalp should be shaved, by which cleanliness is promoted and examina- tion facilitated. Wounds should be treated upon the general prin- ciples enunciated in Volume I. Sutures are often called for, though when the edges of a scalp wound are ragged it would be better not to suture them until all the injured tissue has been cut away and the wound carefully disinfected. All the cephalh®matomata, no matter how exten- sive or deep, which lie outside of the bone are at all times amenable to incision when other treatment fails. Next to the immediate danger from failure to control hemorrhage, the greatest risk run by all of these cases is of failure to take proper antiseptic precautions in the beginning; and of all these injuries, one may say that the fate of a patient lies in large degree in the hands of the man who first treats him. Untold numbers of deaths have been the more or less remote consequences of infection proceeding from wounds improperly treated at first. Injuries to the Cranial Bones. All conceivable degrees of injury to the bones, from a trifling divis- ion of the periosteum down to most extensive denudation or mangling of the external table or the entire thickness of the bones, may be met with. These lesions may be spread over a large area or may be the result of penetrating wounds. In other words, we may have linear, penetrating, or large surface wounds with such injury to the scalp as perhaps to amount to a total loss of covering for the same. All of these, moreover, may be complicated by fractures of the bone at the point of injury, with or without brain lesions, or by other and more remote lesions. In regard to most of these, it may be said that non-penetrating inju- ries, when promptly and properly attended to, have, for the most part, a favorable prognosis. Every penetrating wound of the cranium is a condition justifying grave prognosis, on account of the great danger incurred of infection. Other features of these wounds, with more in regard to prognosis and treatment, will be given under the head of Compound Fractures of the Skull, etc., with which they are usually connected. It is necessary, however, to say in this place that penetrating wounds of the cranium are often received in a way which does not permit actual diagnosis, as, for instance, when received through the nose, the orbit, etc. Every wound whose history and appearance indicate that 28 INJURIES AND SURGICAL DISEASES OF THE HEAD. penetration may have occurred should be, however, subjected to the most rigid scrutiny and care. Points of fencing foils, umbrella tips, etc. have been forced into the brain-cavity through the orbit and elsewhere, in a way which left little external evidence of the severity of the injury. Fractures of the Skull. Following the anatomists, and for general convenience, these are divided into fractures of the vertex, of the lateral region, and of the base, the former being the most frequent, since the vertex is the most exposed. A fracture in a given region may be confined to that locality or may radiate widely or extend nearly around the cranium. Of all the fractures of the bony skeleton, those of the skull constitute about 2 per cent. Fractures of the vertex are, for the most part, due to actual vio- lence, the force being often expended at the point of application or pro- ducing radiating fractures. Those which are limited to the neighbor- hood of the injury are spoken of as direct fractures, in distinction to Fig. 7. Multiple fractures with depression (Bruns). which we have indirect or radiating, often producing remarkable results. Fractures may vary between the simplest crack or fissure, accompanied by but trifling brain-symptoms and never recognized, to the most extensive comminution and destruction of cranial bones which can be imagined. Fissures are practically cracks in the skull, similar to those which may be seen in glass, and are not necessarily followed by the slightest displacement; nor is the entire thickness of the bone always involved, though in the majority of cases the internal table sustains more or less injury. Fissures are often spoken of as linear fractures. They may be straight or irregular, limited to one bone or involving several, single or multiple, and when radiating from a common centre are described as stellate. Splintered or comminuted fractures refer to the formation of numerous bony fragments which are often more or less loosened, some- times completely so, occasionally dovetailed together, and often driven in or depressed. Such fractures are direct. It is possible to have comminution without depression ; the latter makes it the more grave condition. FRACTURES OF THE SKULL. 29 Fractures with absolute loss of substance may be made by gunshot injuries or by any extensive splintering by a penetrating body. It is possible to have fracture of one table without that of the other, this being most often true of the external table. In isolated fractures of the inner table there is often dislodgement of small fragments which may injure the dura and possibly produce later epileptic or irritative disturbance. When the external table is chipped off the diploe is exposed, and this with its wonderfully tine venous communications opens up a wide area to infection and subsequent pyaemia. Gunshot fractures are always depressed and almost invariably com- minuted. The bullet of the modern army rifle possesses a great initial velocity, and the cranium struck by it will probably be disrupted into fragments, with instant death. The majority of gunshot fractures of the skull seen in ordinary civil practice are due to revolver or pistol bullets from weapons of the prevailing type of to-day. In these instances there will usually be penetration, perhaps with perforation of the skull, and the formation thus of one or of two compound fractures, the Fig. 8. wound of entrance being always comminuted and depressed, while frag- ments of bone may be scattered along the course of the bullet, which may also carry in infectious material from without, such as hair, parti- cles of hat, etc. Whatever may be the wisdom of operating in other cases where there is room for doubt as to the proper course, there never is uncer- tainty as to the proper treatment of gunshot wounds of the skull, which should be invariably subjected to operation. It will thus be seen that fractures of the skull may be simple or Gunshot fracture of skull (Helferich). 30 INJURIES AND SURGICAL DISEASES OF THE HEAD. compound, or complicated with other injuries, or depressed, without any reference to whether they are simple fissures or more extensive injuries. On the other hand, depressed and comminuted fractures may occur with- out being compound in a surgical sense, and with each one of these injuries there may be accompanying disturbance of the brain of any degree of severity, from the mildest concussion or shock up to rapidly fatal compression. Any imaginable complication of these head injuries is not beyond the bounds of possibility. Fig. 9. Gunshot fracture of skull (Helferich). The essential features in explaining the mechanism of fractures of the vertex are the area involved and the violence of the impact. The skull is often surpris- ingly elastic, even in the oldest individuals, and fractures occur ordinarily when the natural limits of elasticity have been exceeded and bone-cohesion overcome. Children particularly suffer from depression without fracture, which formerly wyas never operated upon, but which is now regarded as calling for operation. On the other hand, certain skulls are abnormally fragile (see Fragility of the Bones, Chapter XXXV. Vol. I.), and, among the insane, may be found so porous and yielding as to be pressed out of shape without great difficulty. In injuries of slight extent it is enough that the skull be regarded as composed of an elas- tic substance, while for injuries produced by greater violence the skull is to be considered rather as a globe or arch possessed of high resistance and elasticity, whose shape will probably yield more or less before a fracture results. Much may be learned from such experiments as those of Felizet, who filled skulls with paraf- fin and dropped them from varying heights, and then divided the bone, to note in numerous instances that, although the bone had not been fractured, it had yielded at the point of impact to a degree producing a marked depression in the paraffin beneath. It is, then, certain from observation, as well as from a multitude of experiments, that after various injuries, especially to the top of the head, the shape of the skull is momentarily altered and its diameters affected. Many frac- FRACTURES OF THE SKULL. 31 tures, then, .are the result, as it were, of a bursting force, which may be shown by the fact that hair has been found included within closed fissures, as well as even the dura itself. Moreover, particles of bullets have been found within the skull without any visible opening through which they could have entered, showing that the bone has yielded under impact for a fraction of a second. It must also be remembered that in certain injuries to the head, as where a man is struck to the ground, there is injury at two points presumably nearly opposite. Fractures of the skull, especially of the vertex, possess surgical interest mainly as they are accompanied by more or less evidence of intracranial complications. So long as there is no evidence of hemor- rhage or laceration within, they are ordinarily regarded as a feature of the external wound with which they are usually found, and, unless there be comminution, depression, or some other good reason for operating, are covered over as the wound is closed, and are left to the natural pro- cess of repair by formation of minute callus or by the ossification of granulation-tissue. It is absolutely unfair to contrast the results of the surgery of to-day with those of the pre-antiseptic era. Rules then enforced are now entirely abrogated, and the methods of to-day would have made our surgical Ancestors protest most loudly. One respect in which we violate precedent is in our disregard, to-day, of the periosteum or pericranium. This is sacrificed without hesitation when found to be infected or torn or lacerated beyond capability of repair. A flap of scalp, it is known, will adhere as kindly to denuded bone as to periosteum, and we have even learned that skin-grafts can be applied and relied upon to adhere to this same bone—if not upon the first day, a little later when granu- lations have appeared. In the various plastic operations necessitated about the head we may also transplant flaps upon otherwise uncovered bone without the slightest hesitation. We have, furthermore, learned to treat fractures mainly in accordance with what we decide as to intra- cranial complications, or through what we can see either through the wound, if present, or through an opening intentionally made under anti- septic precautions for purposes of exploration. It is everywhere con- ceded to be better policy to remove fragments of bone whose vitality is uncertain, and to sacrifice ruthlessly any tissue injured or lacerated to such an extent that sloughing would probably follow, or so exposed as to have become necessarily infected. Diagnosis of Fractures of the Vertex.—In the absence of an open wound, and unless incision be made, this must often be con- jectural. In the presence of a wound diagnosis is usually easy, enlargement of the wound to any reasonable extent being perfectly legitimate for purposes of examination. In case of a small puncture with suspicion of fracture it will be usually better to enlarge it suf- ficiently to permit the introduction at least of the finger and of careful inspection. With the finger and the eye we seek to detect differences in level, depressions, fissures, etc. Mistakes often arise from the forma- tion of an exudate or a clot, by which a mere depression of the soft parts may be regarded as actual depression of the bone. Error occa- sionally arises from the existence of previous atrophy of the bone or any congenital defects in ossification of the skull; also in the skulls of syph- ilitic patients where disappearance of a gumma is often followed by absorption of the underlying bone. In every case of doubt it will be 32 INJURIES ANI) SURGICAL DISEASES OF THE HEAD. wise to make exploratory incisions, of course under rigid aseptic precau- tions. These should not be made, however, unless the attendant is ready—i. e. has the facilities immediately at hand—for carrying out any further operative procedure that may be necessary, as elevation of frag- ments, removal of foreign bodies, etc. Areas of bloody infiltration often have abrupt margins which are calculated to easily deceive. In children, more especially, we often have a circumscribed bloody tumor which may contain cerebro-spinal fluid rather than pure blood. In some of these cases after exploration there will be found material resembling brain- matter, which, however, is not always such, although real brain-substance may escape, such escape necessarily implying rupture of the overlying membranes. Should it be noted that the fluid used for irrigating and cleansing such a wound begins to pulsate, it will almost always mean connection with the cranial cavity, and, obviously, fracture. A suture should not be mistaken for a line of fracture. This mistake is more easy when Wormian bones are pres- ent. One should not forget that blood may be wiped away from a suture line, but not from that indi- cating fracture. It is not often pos- sible to diagnose an isolated fracture of the inner table. It happened, however, once to Stromeycr to notice that so soon as an injured patient assumed the horizontal position he began to vomit, which nausea sub- sided when he was placed in the upright position. On autopsy it was found that there had occurred a depressed splintering of the inner table with perforation of the dura: less irritation was produced in the upright position than when the patient was lying down, which accounted for his vomiting when in the horizontal posture. When a comminution has been produced it is always of prognostic value to find an unbroken dura, since so long as its integrity is undisturbed the prognosis is better than when the reverse obtains. Prolapse of brain-substance is always a most serious complication. Escape of cerebro-spinal fluid is relatively rare. Treatment.—Treatment comprises attention to the local injury and the suitable dealing with the condition of the brain within when injured, fhe treatment of simple fractures is, for the most part, expectant. In the absence of indication for operation it should be exceedingly simple, and should consist of physiological rest, aseptic dressings, ice applications to the head, the administration of such laxatives, diuretics, antacids, etc. as may be necessary to favor free excretion and to guard against auto- intoxication. Whenever there is reason to suspect a depression, explora- tory incision at least should be made. Actual depression, whether the fracture be compound or not, calls always for operation, the opinions of Fig. 10. Depression of inner table (Bruns). FRACTUE.ES OF THE SKULL. 33 surgeons of past generations to the contrary notwithstanding. This course is justified by the numerous instances in which later consequences have been noted, such as traumatic epilepsy, insanity, etc. Compound injuries call always for operation of some character, in- cluding the removal of loosened splinters, the elevation of depressed bone, the removal of all foreign matter, the checking of hemor- rhage, the excision of bruised and lacerated tissue, and the proper closure of the wound, with or without drainage according to circum- stances. In many serious and lacerated cases it is inadvisable to close the wound with the view of attempting primary union. It is much better to pack it with gauze and temporarily close it with secondary sutures. All of these surgical measures should be seconded by efforts which every judicious surgeon will always put into practice—namely, physiological rest (quietude of the head, which may even be enforced by the posterior plaster-of-Paris splint to the head and neck), attention to the primes vice, the avoidance of transportation, the prevention of auto-intoxication, etc. The best judgment will often be called for in decision as to the amount of bone to be removed, the wisdom of opening the dura when not lace- rated, of examination of the brain with the exploring needle, the matter of drainage, the time during which it shall remain, etc. With reference to all these matters exact rules cannot be given, but every case must necessarily be decided upon its own merits. When drainage is made in recent cases it is usually sufficient to drain the scalp wound. Only in cases where there is probability of meningeal infection does it pay to deliberately attempt to drain the dural cavity. This is perhaps better done with gauze than with drainage-tubes. Skull-fractures where the injury is limited to a small area are now treated according to a bolder method than wras in vogue a number of years ago, especially in cases where depression is recognized. I believe thoroughly in caref ul and judicious operating in every case where distinct depression can be made out, as well as in every case wdiere indications point to injury of parts within the bone. The statistics of trephining in the pre-antiseptic era are valueless as arguments in this consideration. If done according to strict aseptic precautions and if good surgical judg- ment be used in every respect, the operation is per se almost devoid of mortality, and should not be regarded as a last resort, but rather in such cases as a first one. I have myself seen so many instances of later untoward consequences resulting from delay, which corroborate the expe- rience of others, that I wrould not be misunderstood in this matter. My advice might perhaps be summed up in the following words: Where there are no brain-symptoms and no skull-symptoms in fractures of the vertex leave the case alone; when either of these is present, especially the former, it will alivays be wise to operate. The question of how far interference, or how much of exploration, maybe per- mitted when the brain itself is injured is another to be decided only upon its merits. So far as gunshot injuries are concerned and the removal of missiles, it will prob- ably be the safest rule to follow that only foreign bodies which appear on or near the surface or which can be easily or definitely located call for removal. So far as other interference with the brain is concerned, it must be decided mainly on the brain-symptoms and upon the special localizing symptoms, all of which are yet to be considered. 34 INJURIES AND SURGICAL DISEASES OF THE HEAD. In most of these fractures the violence is applied at some more or less distant point, and, by transmission through the arch-like structure of the skull, expends itself in Assuring or comminuting the base. The most frequent location of the indirect injury is upon the convexity. The mechanism of these fractures, indirect as most of them are, has been a vexed problem for many centuries, but has been cleared up mainly within the present century. Felizet has shown, for instance, how the handle of a hammer maybe forced into its head by striking it in either one of two different ways, and has compared the mechanism of basal fractures to this fact. The secret of basal fractures probably resides in the elas- ticity of the skull, which varies within wide limits in different individ- uals, and which breaks, as do the ribs and the pelvis, at points more or less distant from that at which the injury occurred. Were the skull Fractures of the Base of the Skull. Fig. 11. Fracture of base of skull (Bruns). everywhere equally thick and elastic, there would be much less variation in these fractures, but we know that lacerations frequently extend be- tween the most resistant parts; and when violence is applied upon the forehead we commonly find that the resulting fissure extends between the crista and the wings of the sphenoid upon the same side in its course toward the base : that when the lateral region of the skull is injured the fissure commonly extends between the sphenoidal wings and the occip- ital bone; and that when the occipital region receives the first injury the fracture lies usually between the pyramid and the occipital crests. The analogy between fractures of the skull and cracks made in nutshells (cocoanuts, etc.) when struck with a hammer is too self-evident to be lost PLATE I. Fractures of the Base of the Skull. Illustrative Lines of Fissure or Fracture are printed in Red. 35 FRACTURES OF THE BASE OF THE SKULL. sight of. Many years since the French introduced the term f racture by contre-coup (counter-stroke)—a practical admission of the occurrence of fracture at a point more or less opposite to that struck. In 1884, Aran formulated the following conclusions, which will probably stand to-day undisputed: 1. The great variety of indirect fractures of the base (by so-called contre- coup) are in reality fractures propagated from vertex to base—i. e. fractures by irradiation. 2. Fractures reach the base from the vertex by the shortest anatomical route, traversing fissures in their course. 3. There is a relation between the region of the skull first injured and the seat of the basal fractures. Accepting the anatomical division of the inner basal sur- face of the cranium into three fossae, it may be said that lines of fracture occupying either one of these fossae are likely to be produced by violence applied to the corresponding region of the vertex. There is, however, no certainty about these fractures, and to spend further time in this connection in studying these minutiae would be of little avail to the student. It will be enough to add, then, that exten- sive fissures of the vertex are almost always extended to the base of the skull, while the reverse is seldom true. There are doubtless also many cases in which a bursting force compromises the bone rather than mere radiation of unexpended violence; but so long as skulls conform to no fixed mathematical figures nor proportions, but are composed of bones varying in shape, density, and strength, ij: will be impossible to formu- late any laws which are comprehensive enough to be satisfactory. Frac- tures in the posterior fossh occurrfor the most part through violence applied posteriorly and frbm below. There is a ring-form of basal fracture produced mainly the-irftpact of the vertebral column, as when an individual falls upon 'tub weight of the body forcing the cranial base in upon the brain. Fractures of the anterior fossa may involve the roof of the orbit; even facial bones may participate in the injury. These considerations are not without importance, since if a patient presents symptoms of injury of the petrous bone, and if these be accompanied by injury to the lateral region of the skull, we are in position to make a diagnosis of fracture of the middle fossa. (Vide Plate I.) By all means, the majority of basal fractures are mere fissures which open and dose instantly upon their production—close so quickly, in fact, as scarcely even to include blood between the broken bony surfaces. Prognosis.—The majority of basal fractures arc fatal, cither because of injuries to the brain, or of hemorrhage or violence along the nerve- trunks, or from infection extending along the newly-opened paths. Other things being equal, the longer the fissure the greater the danger, particularly so when it takes its origin in the vertex, and because of greater ease of infection. Air-infection may incur in any basal fracture by fissures extending into the various air-containing cavities—nose, ears, sinuses, etc. They are then practically compound, though invisible. The general prognosis will depend, first, upon the injury to the cranial contents; second, upon the possibility of infection. Statistics are abso- lutely unreliable, although always possessing interest. Numerous museum specimens show the perfection with which bony repair may occur and the admirable way in which compensation is afforded for 36 INJURIES AND SURGICAL DISEASES OF THE HEAD. defects. Suppuration after basal fractures is mainly that due to puru- lent basal meningitis, in which case the brain-symptoms dominate in the clinical picture, while the appearance of a single drop of pus in the ear or upon the surface is of the greatest significance. The conversion of a serous outflow (e. g. from the ear) into purulent fluid is also pathognomonic. Various paralyses, principally of the cranial nerves, may follow this injury and prove temporary or permanent. Diagnosis is often made by the study of these special nerve lesions. Diagnosis.—The most significant diagnostic features are— 1. Spread of blood from the point of fracture until it appears as an ecchymosis at certain points beneath the skin. This will occur early in some cases, late in others. It may appear beneath the skin or beneath the conjunctiva or other mucous membranes, even in the pharynx. Occurring about the mastoid, it implies fracture of the middle or pos- terior fossa ; about the eyelids, of the anterior fossa. Beneath the bulbar conjunctiva, it means extravasation along the optic sheath, probably from within the dura. In fractures of the posterior fossa it will come to the surface of the neck, but only after two or three days. The ecchymoses about the lids or orbits occurring after two or three days mean more than those occurring within these days, since the latter may be caused by external bruising. The globe of the eye may be pushed forward by blood accumulating within the orbit. Exophthalmos thus produced is therefore most significant, though not common. 2. Escape of serous fluid, blood, or brain-substance from the cavities of the skull. Hemorrhages from this cause occur most often from the ear, the petrous bone being tunnelled with various canals through which blood may thus escape. One should, however, assure himself in every instance that the blood is really escaping from the ear, and not from some trifling wound of the external soft parts, the soft walls of the meatus, or the tympanum itself. Profuse hemorrhage can probably only come from a basal fracture. Escape of serous fluid is usually noted as a sequel to hemorrhage, although it may begin almost immediately after an injury. Rarely more than twenty-four hours elapse before it begins to flow, if at all. The quantity of fluid discharged is sometimes aston- ishing. It may occur in frequent drops or during expulsive efforts, like coughing, or may ooze in such a way as to be insensibly collected by the absorbent dressings. In average cases the amount in twenty-four hours is from 100 c.c. to 200 c.c. : 800 c.c. have been noted in occasional instances, and in a very few still more. Cases characterized by escape of fluid from the ear usually belong in one of the following categories : (а) Those in which there is copious and continuous discharge setting in early after injury, in which one may with reason suspect a fissure of the petrous bone extending into the subarachnoid space. (б) Cases where the escape does not occur until the second day, and which are preceded by hemorrhage. (c) Those in which a small quantity of fluid trickles slowly away, either with or without previous hemorrhage. Here diagnosis is uncer- tain, but prognosis is good. In other instances the fluid may escape through the Eustachian tube into the pharynx, whence it may escape by the nostrils or be swallowed. FRACTURES OF THE BASE OF THE SKULL. 37 The escape of brain-substance is rarely noted, and obviously implies such serious injury as to make the prognosis of the worst. 3. Disturbance of function along particular cranial nerves, paralysis of which is often produced by fractures of the base, particularly those involving the foramen of exit of the nerve involved; in which case the nerve may be lacerated or injured by the fragment of bone. 4. In addition to these distinctive features there will be in the majority of instances brain-symptoms, either of contusion or compression, varying in severity within all possible limits, but adding their weight to the value of the testimony. These will soon be considered by themselves. Other and unusual signs of basal fracture may occur, such as com- munication between the cavities of the petrous bone and the mastoid cells, and leading to the formation of pneumatocele, or emphysema of the overlying soft parts, observed mostly about the orbits, where the nasal cavity is as well involved. Treatment.—The treatment of basal fractures is mainly symptom- atic. The tirst effort should be to make antiseptic all those parts of the skull involved, which means to shave the scalp; to thoroughly cleanse and irrigate the external ear and the auditory meatus, using a head mirror and ear speculum for this purpose, if possible; to tampon the meatus with antiseptic cotton ; to provide a copious absorbent dress- ing for such fluid as may escape, and to change this frequently; to cleanse the nasal cavity so far as possible, as well as the conjunctival sac when necessary, for all of which the peroxide of hydrogen is most serviceable. All of this should be done promptly, while at the same time studying the patient for evidence of brain injury or of involve- ment of special nerves. By the time these measures are thoroughly carried out a decision at least as to the necessity for immediate operation should have been reached. Evidence of brain-compression wanting, and in the absence of external or compound injury, the patient may be left at rest, with cold applications to the head and active purgation. In many of these instances benefit follows the application of a number of leeches to the mastoid region and to the occiput. Operation is called for later only when brain-symptoms supervene, these consisting for the most part of evidences of compression, either from blood or from pus, since com- pression from other causes must have been acting at the time of the first examination, and should have been recognized at that time. When direct fractures are evident the possibility of the entrance of foreign bodies must be also remembered. Thus, penetrating fractures of the base have occurred through the orbit as the result of accident or assault, and such weapons or implements as foils, ramrods, drumsticks, canes, umbrella points, etc. have been known not only to penetrate into the brain, but perhaps to leave some portion of their substance—e. g. a foil tip or an umbrella tip—within the cranium after their withdrawal. These are cases which call for special and delicate manipulation not comprised within the ordinary treatment of basal fractures. They are usually compound fractures of the base, and are mentioned here mainly to illustrate the judgment and surgical acumen that may be called for in many of these instances. These are, of course, cases justifying more or less extensive incision and exploration, as well as necessitating the removal of a foreign body when present, since its remain- ing would in all probability entail either a prompt meningitis or later brain- abscess. 38 INJURIES AND SURGICAL DISEASES OF THE HEAD. Separation of sutures, known also as diastasis of the same, is the occasional result of injury instead of, or complicated with, fissures or other fractures. It is the result of violence, and is virtually a specific form of fracture, from which it differs in no essential particular. Dias- tasis can only take place along lines of previous suture, but it is possi- ble that Wormian bones may be thus loosened. Sutures thus separated ordinarily heal by fibrous repair rather than osseous union. Diagnosis is ordinarily possible only as they are exposed to view, although dis- placement in the middle line or along known suture lines may be per- haps regarded as diastasis. The treatment differs in no respect from that of other fractures. Injuries to the frontal sinuses occasionally complicate fractures of the skull. These sinuses vary exceedingly in different individuals; are rarely truly symmetrical; are not found in the very young; they con- nect with the nose in such a way that emphysema of the frontal region is quite possible, while air may even be blown beneath the periosteum or may communicate with the interior of the cranium. In wounds of the frontal region the sinuses are occasionally opened—a fact of import- ance, since infection of the Schneiderian membrane may occur and endanger life, mainly because of the retention of infectious products within its cavities. Moreover, by such wounds the ethmoid may also be injured. Pus which escapes from these sinuses and from the ethmoidal cells is usually thin and bad-smelling. Long continuation of suppura- tion after such injuries probably means necrosis and formation of sequestra. With the recognition of certain portions of the brain whose function is now generally recognized and described, as well as with the more exact knowledge regarding the entire encephalon, the outcome of many recent studies, the teaching of the past with regard to the nature of various brain lesions has been essentially modified. Especially is this true with regard to the distinction formerly emphasized as between concussion and compression. In discussing brain injuries we must, first of all, distinguish between traumatic disturbances of the entire endo- cranium and localized injuries to the brain or particular vessels and nerves entering into its composition. With regard to the first, it is possible that the entire blood or lymphatic circulation within the cranium may be affected in such a way as to influence its nutrition and function, by which means activity and function are mildly or seriously perverted. The immediate effect of severe injury to any part of the body is reflex vasomotor spasm, which constitutes the essential feature of the condition known everywhere as shock. It is this condition, with its strong local expressions, which used to be known as concussion of the brain. When studied upon its merits, it is found to be indistinguishable from shock pro- duced by injuries to other parts. It will be correct, then, to make the general statement that the condition for so many years taught and recog- nized as concussion is but shock following injury to the head. This makes no further demands upon the question of pathology than those prompted by any traumatic disturbance. INJURIES TO THE BRAIN AND ITS ADNEXA. CONCUSSION OF THE BRAIN. 39 Through the mechanism of the cerebro-spinal fluid rapid alterations of pres- sure and of the volume of the brain are produced. There is an easy path between the inelastic cranial cavity and the exceedingly elastic and accommodating spinal canal, which latter serves as a reservoir for the fluid which may be pressed out of the cranium when brain-pressure is increased. And, while the subdural and sub- arachnoid spaces are each of them absolutely closed sacs and do not communicate one with the other, there, nevertheless, is ample accommodation within each to permit a constant equilibrium of pressure under ordinary circumstances, as between the spinal cord and the cranial canal. The brain expands in volume with every systole of the heart, while with every diastole it contracts. Its size is, moreover, modified by the motion of respiration. Under these extremely accom- modating conditions it is scarcely credible that external injuries which leave no internal marks of violence should do anything more than disturb the equilibrium of fluid distribution. Concussion of the Brain. We inherit tjie term concussion from the earlier masters of our art, by whom, however, it was used in a much broader sense than of late. Its modern significance was given to it by Boirel, who made it apply to a group of cerebral symptoms the result of injuries not accompanied by fracture or perceptible laceration of vessels—symptoms varying in inten- sity and duration. In 1705 the subject was first studied anatomically, and then by Littre, whose inferences were natural from insufficient investigation, and who ascribed trifling alterations of brain-tissue to the inevitable results of serious injury to the skull. Later, Petit formulated the statements which until recently have been generally held, that as the result of external violence vibrations are produced which are continued to the brain-substance and cause oscillations or other trifling molecular changes. There has always been this difficulty, however, that concussion was rarely followed by death—that the injuries which were followed by recovery could not be accurately estimated, while after those which were followed by death the brain was almost invariably found the subject of at least minute disturbances, such as capillary hemorrhages, trifling lacerations, etc. The physiologists have taught us that the most minute injury—at least in certain parts of the brain—is enough not only to disturb, but to destroy, function ; and we can maintain with probable accuracy that in so-called fatal cases of concussion we have to do with something more than mere molecular disturbance without discoverable effect. Moreover, from mere oscillation we have the right to expect that after the lapse of a certain time there should be complete or almost complete repair; in which hope, however, we are disappointed so far as clinical experience goes. And so it has happened that the theory of communicated vibrations, so long unchallenged, has of late been almost completely abandoned, at least in those cases which are followed by long- continued or permanent disturbance. Experimentation upon animals has done a great deal to lead to this change of view, it being found that any injury to the head which seriously disturbs function of the brain gives appearances of congestion of membranes or of the substance of the brain, with minute vascular ruptures, trifling lacerations, etc. The most valuable researches in this connection have been con- ducted by Duret, who has apparently proven that when an impression is made upon one side of the skull, even though it be instantaneous, produced by a blow, it is followed by elevation at a point opposite, permitted by the elasticity of the bone. There occurs also a violent precipitation of the liquid contained within and around the brain in the direction of the injury, with damage to the vessels and even the substance of the brain. These separate traumatisms he divides into three stages: a. Of excitation ; b. Of paralysis; c. Of reaction; during the first of which there is a tetanic condition of muscles, often with violent expulsion of urine and fseces, increase of vascular pressure, and irregularity of the heart. This stage, sometimes only a few seconds in duration, is succeeded by the 40 INJURIES AND SURGICAL DISEASES OF THE HEAD. paralytic stage, marked by vascular relaxation, insensibility, rapid respiration, temporary paralysis of muscles, etc. The third stage is characterized by elevation of temperature, and often by mental excitement, merging even into delirium or mania. Our present position is practically this : The possibility of pure con- cussion of the brain—i. e. disturbance of brain function without gross mechanical lesions—is admitted, but its general frequency is denied. When present it must either pass away quickly, the condition being equivalent to that called “stunning” by the laity, or, if it assume dis- tinct form, its signs and symptoms are indistinguishable from those of shock, consisting essentially of rapid and feeble pulse, quick and shallow respiration, pallor of the skin, copious perspiration, complete or partial unconsciousness, muscle inco-ordination, with lack of sphincter control, occasional vomiting, the pupils usually reacting to light. The treatment for this condition is essentially that for shock, plus whatever may be called for in the way of attention to injuries about the head—e. g. sewing up a scalp wound, etc. Contusion. The condition of shock (cerebral concussion), when of pure type, passes away with reasonable promptness, especially when aided by sur- gical treatment. Anything which persists in the way of muscle-paralysis, disturbance of function of nerves of special sense, or other sign of any importance, indicates something more than mere vibratory disturbance: it implies mechanical lesion which could be perceived by the eye were the parts exposed, and constitutes the condition now generally known as contusion. This implies the existence of trifling exudates or hemor- rhages, which require not only absorption, but even cicatrization. Con- tusion pure and simple differs from ordinary laceration as a contusion else- where may differ from a wound. It cannot be separated, however, from conditions in which there are minute separations of continuity and actual lacerations. It may be divided into three post-mortem forms: general hypercemia, with or without oedema; punctate or miliary hemorrhages; and thrombosis of minute vessels, which may occur separately or together. Moreover, there may exist similar lesions in the meninges, constituting meningeal contusion. Ordinarily, minute vessels of the pia are ruptured and blood is effused in small and thin patches over various parts of the brain. The so-called compression apoplexies of certain authors are insep- arable from the conditions above described. Such minute blood-clots are only to be distinguished upon very careful sectioning of the brain, and are found most often in the region of the medulla and along the floor of the fourth ventricle. They are probably caused by the forcing into the fourth from the lateral ventricles of the fluid contained in the latter. Symptoms of Contusion.—When the ordinary symptoms of shock which follow all severe injuries to the head, especially when the deep lesions are not too severe, fail to disperse in a short time under proper treatment, and when, in particular, new and irregular symptoms are superadded to those of shock alone, we have every reason to think that the intracranial condition is one of contusion rather than of shock. When, for instance, mental agitation changes into delirium, when the BRA IN-DRESSURE OR COMPRESSION. 41 rapid, feeble pulse becomes stronger and slower, the respiration deeper, the limbs moved in inco-ordinate ways, the speech disturbed from muscle inco-ordination, the patient selects wrong words, or when the mental condition becomes more serious and stupor or coma takes the place of delirium, while external irritants have less and less effect, and when the pupils gradually enlarge while failing to respond to light,— we may say that the condition of contusion is making itself apparent. If along with muscle-uncertainty there be also muscle-spasm or rigidity, with fixation of the fingers in the athetoid position, the evidence to this effect is increasing. If with all this the thermometer fails to show that an active inflammatory condition—i. e. meningitis—is prevailing, the diagnosis may be regarded as certain. Error may possibly arise when there are evidences of alcoholism. Coma following head injury ought not to be ascribed to the alcoholic condition except by the strictest pro- cess of exclusion. Temperature alone will be of the greatest service in this direction, since in alcoholism it is usually subnormal. In apoplexy and non-traumatic hemorrhages it is also usually subnormal at the com- mencement of the attack, rising to normal, and remaining there if the patient recover, but continuing to rise in cases where the prognosis is bad. The treatment of brain contusion must be managed largely in response to special symptoms. Physiological rest, attention to scalp wounds, fractures, etc., shaving of the scalp, application of ice to the head, with such stimulation to the heart as may be necessary in extreme cases by subcutaneous administration of strychnia, atropine, etc., by local fomentations over the epigastrium, or by immersion in a hot bath when surroundings permit it,—these in a general way constitute most of the methods of treatment in contusion. When only symptoms of diffuse and minute lacerations can be recognized, the use of the trephine is impracticable, even unjustifiable, save when indicated by some exter- nal marking—i. e. compound fracture or the like. When localizing symptoms are present the trephine is, of course, called for. When the skull injury is recognized as a basal fracture, venesection or the appli- cation of leeches behind the ears will be most serviceable. In every such case there is the greatest necessity for regulating the excretions and preventing auto-intoxication. For this purpose diuretics and laxatives must be used, often in conjunction with intestinal antiseptics. The catheter should be resorted to whenever indicated by the condition of the bladder, which should be carefully watched. As the days go by and patients lie more or less helpless and inert, the greatest care should be exercised for the prevention of bed-sores. When, still later, patience is tried to the utmost because mental inertness, muscle-rigidity, etc. fail to disappear, I would advise the use of potassium iodide internally, having seen great benefit from its use in many cases, although acknowledging that it is given on purely empirical grounds. Brain-pressure or Compression. That the cranial contents—brain, blood, lymph, and cerebro-spinal fluid—completely fill the cranial cavity has been already amply shown, as well as that there is no room for anything in the shape of a foreign body without seriously affecting the equilibrium between the brain and 42 INJURIES AND SURGICAL DISEASES OE THE HEAD. the contents of the spinal canal. When, however, any foreign substance exerts pressure upon the brain, the results are invariably the same, be this substance what it may, and compression signs are always the same, no matter what the compressing cause. Reduction in size of the cranial cavity—i. e. compression—may be produced— 1. By altering the circulation of its surroundings (e. g. depressed fractures or by direct pressure); 2. By increase in the quantity of cerebro-spinal fluid or of the vol- ume of the brain, which latter may be produced by oedema, by serous exudate, or by actual hypertrophy ; 3. By foreign bodies, which may enter the skull from without; 4. By pathological conditions—collections of blood or pus, tumors, etc., which may be produced either from the brain-substance, its con- taining bone or membranes, or its vessels. In every one of these conditions the size and tension of the brain are affected. The cerebro-spinal fluid is mainly involved in acute, not in chronic, conditions. Avery slow reduction of the diameters of the skull produces such slow alterations of pressure as to cause a minimum of disturbance. So far as compression from traumatic influences is con- cerned, we distinguish mainly between— 1. Compression by extravasation of blood ; 2. By fractures of the skull with depression, or by foreign bodies penetrating from without; 3. By products of acute infectious inflammation due to septic infec- tion from without. The result common to all of these is increase of intracranial tension, and its consequence is a less rapid flow of blood and an altered blood- supply to the brain and its membranes. Experiment has completely established that in compression of the brain cere- bro-spinal fluid is forced by pressure into the spinal canal, whose membranes are more elastic, and which thus help to accommodate it; but it has been clearly established that compression of the brain by one-sixth of its volume of any mate- rial is essentially fatal, and that much less is at least serious. That fractures with depression produce sometimes serious, at other times trifling, symptoms is due largely to the varying accommodation of the spinal canal. Both experiment and observation alike seem to confirm the view that consciousness pertains to the cortex as a whole, and that unconsciousness is an inhibitory or paralytic condition which is produced in compression. Temperature is a matter of great importance in studying compression and foretelling its consequences. Elevation of temperature is an early, continuous, and constant symptom in these cases. If temperature be subnormal and subsequently rise, prognosis is bad. Variations of tem- perature are more reliable guides than conditions of consciousness. As Phelps has remarked, in no condition except sunstroke is temperature so uniformly high as in cases of serious encephalic lesions. Symptoms.—As indicated above, the symptoms and signs of com- pression are practically identical, no matter what the compressing cause. When this cause acts instantly there is no time afforded for differentia- tion, but when it occurs slowly we note the following symptoms, and about in the order as here presented : Irritability or restlessness ; visceral disturbances ; pain ; intense cephalalgia ; congestion of the face ; narrow pupils; augmented pulse, often seen in the carotids. If compression BRAIN-PRESSURE OR COMPRESSION. 43 occur more rapidly, torpor quickly succeeds erethism, after which patients vomit, have convulsions or at least convulsive motions, speech is dis- turbed, and stupor comes on, from which they neither awake nor can be awakened until the compression is relieved. All of these indications refer to involvement of the cortex, which is generally regarded as the seat of consciousness as well as of projection and imagination. During the night of the senses produced by pressure upon the cortex only the automatic basal apparatus and that of the spinal cord continue in more or less disturbed operation. Of all the general functions, consciousness vanishes first and returns among the last. When intracranial pressure has reached a certain point, epileptiform convulsions result, varying in intensity, affecting all the limbs, and terminating perhaps with rigidity. These are an expression of high pressure. Similar convulsions occur in various head wounds, explanation for which is the result of pressure, which, though not extensive, may produce alteration in the circulation with its disastrous consequences. The later and constant evidences of compression, and those which in aggravated cases supervene at once, are reduction of pulse-rate, due to the action of the pneumogastric, which suffers first an irritation and later a paralysis. The pulse becomes not only slackened, but full; the respiration-rate is correspondingly reduced, so that breathing during coma is deep, slow, and often stertorous. This feature of stertor is an expression of paralysis of the palatal and pharyn- geal muscles, which flap, as it were, in the air-current. Vomiting, which may occur before brain-tension has risen high, is not met with in the most serious cases. Coma is absolute, and nothing can arouse the patient. Along with these signs, the most important other indications are the paralyses, which may consist of monoplegia, hemiplegia, or paralysis of individual muscle-groups according as pressure is made upon a limited area or upon an entire hemisphere. By the division of the cranial cav- ity by the falx and the tentorium it is divided into three chambers, in any one of which pressure may be more manifest than in the others. Nevertheless, a serious compressing cause will affect the tension of the cerebro-spinal fluid and produce general expression of pressure. The pupils often vary, and responsiveness to light is occasionally noted. Nystagmus and ocular rotation may be occasionally seen. Choking of the optic disk is also a frequent phenomenon, to be recognized only upon ophthalmoscopic examination. This is due to pressure in the subdural and subarachnoid prolongations along the optic nerve. In milder cases of chronic compression disturbances of vision are of very great clinical importance. These pertain especially to diagnosis of hydrocephalus and of brain tumors. When they occur immediately after injury, and re- main, they depend upon laceration or other severe injury of the optic nerve. Those which quickly disappear depend mainly upon pressure of blood, which is reabsorbed, while those which are later in their appear- ance depend upon later intracranial complications. A unilateral lesion of the optic nerve depends most often upon injuries to it within the optic canal. When the lesion is bilateral the cause lies deep. General paral- ysis may be of the type of hemiplegia, single or double ; i. e. by “ double ” I mean paralysis of the entire voluntary musculature of the body, which necessarily implies serious, too often fatal, hemorrhage. 44 INJURIES AND SURGICAL DISEASES OF THE HEAD. PROGNOSIS:V—This depends in large degree upon the nature of the compressing e#use and of the possibility of its removal. While the -nature'--of the tfeame may ordinarily be determined, how much can be -onI pitslied' 1 >y way of removal may often not be foretold before the operation at which this should be attempted. In every acute case it is desirable to make this attempt early, since high pressure, which may be borne for a few moments, is fatal if continued. Compression to any serious degree, left unattended to, is usually fatal. So soon as paralysis in circulatory and respiratory centres is apparent the beginning of the end is at hand. Another reason for hastening operation, when indicated, is that acute softening of brain-tissue comes on promptly, as well as general cerebral oedema, which has destroyed many a patient from the second to the fourth day after injury. When the pressure is localized, especially upon a limited area, this may suffer intensely, and the balance of the brain to a minor degree. So soon as this local pressure be relieved and circulation restored resumption of function is quite pos- sible. Incomplete paralyses are the final results of extravasations, which often seem to be localized with sufficient accuracy to warrant operation. In some instances the brain appears to acquire tolerance for pressure when not too serious. This is shown by recovery, especially of children, after injuries which have left them unconscious for days. ( Vide Plate II.) Treatment.—The treatment of compression is summed up in one phrase—i. e. to remove the cause when possible. The only cases in which this rule may be safely disregarded are those where the attempt to remove the cause means more danger than to leave it unremoved. This is not true, however, in the ordinary cases of bone depression, men- ingeal hemorrhage, etc. Before operation, however, or as a substitute for it in cases of minor severity, it may be well to assist venous outflow by venesection, by which blood-pressure is reduced. In these cases this may well be done from the temporal veins or external jugulars, with the patient in the semi-upright position. Drastic purgatives may also be employed in order to utilize intestinal outpour as a stimulation to resorp- tion of cerebro-spinal fluid. The physiological action of cold (ice-bags) may also be secured for the purpose of contracting the cerebral arteries. But all these measures are only to be resorted to when there is uncer- tainty as to the wisdom of operating, since when operation is clearly indicated it should be done at once, and should take precedence of every- thing else. This operation means ordinarily the procedure to which the now general term trephining- has been applied by common consent, and comprises any measure by which the skull is opened at a suitable place and the dura or the underlying cortex exposed to such extent as to permit removal of the compressing cause. Whether the opening be made with trephine (annular saw) or with the straight or revolving saw, with bone-chisel, with bone-forceps, or with anything else is a matter of choice on the part of the operator. So, too, removal of the compress- ing cause should include the elevation of depressed bone, the removal of dislodged particles as well as of all foreign bodies, the cleaning out of blood- clot, the checking of hemorrhage, and the closure of the wound, with or without drainage or counter-opening at some other part of the skull, as may seem wise in special cases. This entire procedure comes now under the name of trephining, and must be painstakingly gone through with in most instances. PLATE II. FIG.I. FIG.2.

INJURIES OF INTRACRANIAL VESSELS AND SINUSES. 45 The operative manoeuvres will be discussed by themselves in another portion of this chapter. Injuries of Intracranial Vessels and Sinuses. Intracranial hemorrhages may occur— а. From external sources through the broken bone or between it and the dura (extradural); б. Beneath the dura, between or into the membranes (subdural); c. Into the brain-substance proper or the ventricles (subcortical or intraventricular). The vessels whose injuries are most often under consideration are the meningeal arteries, the sinuses, the small vessels of the membranes, and, in very rare cases, the internal carotid. The arteries, like the sinus-walls, may be ruptured either by substances forced in from without or by sheer laceration. The longitudinal sinus is most liable to injury from without. When this sinus is exposed it may be dealt with either by suture if the wound be small, or by ligation, or by tamponing with iodoform gauze. Fig. 12. Compression following hemorrhage from the middle meningeal artery (Helferieh), Hemorrhage from this source is ordinarily not difficult to check. Fatal air-embolism has resulted through an opened sinus not properly plugged. The other sinuses are very rarely injured, as by gunshot wound, fracture of the base, etc. The sinuses have also been injured by compression of the skull during parturition. Bleeding from the sinus is usually indis- tinguishable from that from a meningeal artery, save that the former occurs more slowly. 46 INJURIES AND SURGICAL DISEASES OF THE HEAD. Injuries to the middle meningeal artery naturally occur in the immediate neighborhood of this vessel, which is not infrequently rup- tured by contre-coup. The artery runs sometimes in a groove of the bone, sometimes in the dura, and sometimes entirely in the bone. The more it lies within the bone, the more likely it is to be ruptured when this part of the skull is fissured. Basal fractures often follow the groove for this artery. The anterior branch is more often injured than the pos- terior. Extravasations from this source are more common than from all others combined, the amount of blood varying within wide limits. Two hundred and forty grammes of blood-clot have been known to collect, and the dura to be separated down to the very base of the skull. I have repeatedly taken away at least a small teacupful of blood-clot in such cases. The symptoms of this hemorrhage are, of course, those of com- pression, while extravasation may be rapid and quickly fatal, delayed for some time, or may take place in two stages, the first but slight and producing no coma. New clots are always dark and disk-shaped, thick in the middle, with a definite margin. As the clots become older they become more adherent and difficult to remove. The symptoms of meningeal hemorrhage consist of an interval of consciousness or lucidity after injury, followed by epileptic or spastic symptoms, alterations in the pupils and pulse, unconsciousness passing into coma, and stertorous respi- ration. There may or may not be external evidence of head injury. The character of the paralysis (hemiplegia) may indicate that the clot is really upon the side opposite to that of the skull which shows evi- dence of injury. In this case arterial laceration is the result of contre- coup. According to the rapidity of the symptoms is the extent of the primary lesion. Meningeal hemorrhages involve immediately the motor area, which makes diagnosis all the easier. Treatment.—The majority of these cases are fatal when left alone. Hence the treatment is essentially operative, and should be prompt. Of 257 cases collected by Wiesman, 147 were treated expectantly, and of these 131 died ; while of 110 cases operated on, only 30 died; and this mor- tality-rate could be greatly improved upon in favorable cases. Nothing could speak more eloquently for operation than such statistics. The skull should be opened in the indicated area, clot removed, bleeding vessels sought for, counter-opening made in cases where the clot is very large, and drainage established through and through. One of the earliest and most instructive cases on record as corroborating bold measures in these cases was that reported by Parker, who in the absence of exter- nal indication, inferring that he had to do with meningeal hemorrhage, trephined first on one side, and, finding no clot, trephined again upon the other side: here, finding nothing between the dura and the bone, he incised the dura, removed a large extravasation, and saw his patient completely restored to health. This was so late as 1877, at which time it was regarded as an exceedingly bold procedure; which will show what rapid advances have been made in cerebral surgery. It is more important to remove the clot than to find the artery. Consequently, the trephine should be applied at the point most indicated by a study of paralysis. In other words, the principles of cerebral localization should guide, rather than those of arterial anatomy. Injuries to the carotid within the cranium are exceedingly rare. Still, it has been injured in basal fractures and penetrating wounds. LACERATIONS AND INJURIES TO THE RRAIN-SUBSTANCE. 47 Development of arterio-venous aneurisms after basal injuries is occasionally noted. They will give rise occasionally to pulsating exoph- thalmos. Pulsating tumors within the orbit which push the eye for- ward not infrequently occur after serious head injury. Of 77 cases col- lected by Riving ton, 41 had a traumatic origin. Subdural hemorrhages are not infrequent in the skulls of the new- born, and constitute the so-called apoplexia neonatorum. They may occasion convulsions and paralyses of irregular type, while if the extrav- asations become infected multiple abscess may result. In adults subdural hemorrhages are, for the most part, connected with those brain lesions which have been already spoken of as contusions. They may be the starting-points for pachymeningitis. Their most common results are disturbances of consciousness and mentality. Paralytic dementia follows in some of these cases. Extensive subdural hemorrhage may give a clinical picture corresponding to extra- dural. Disseminated minute ecchymoses constitute minute focal lesions, which are, however, usually so distributed as to confuse and prevent accurate diagnosis. Apoplexy or intraventricular hemorrhages, especially from the lenticulo-striate artery (Charcot’s “artery of hemorrhage”), have until very recently never been regarded as warranting surgical interference. Of late, however, especially in the ingravescent or progressive forms, ligature of the common carotid has been of some service, though in order to render this effective ligature must be made very early in the course of the case. Traumatic intraventricular hemorrhage occurs in much the same way as meningeal, by contre-coup. Individuality of symptoms is lost in the general comatose condition of the patient, but when operation is performed, as it is usually best to perform it, if no extradural clot be found and if brain-tension be evidently increased, the dura should be opened; after which, if no subdural clot be seen, the ventricles should always be tapped with the exploring needle. In this case, if blood be removed by aspiration, a knife should be passed directly into the ven- tricle, after which blood will promptly escape, if present. Dennis was the first to diagnose the presence of intraventricular clot and to deliber- ately incise into it, and I have myself repeatedly imitated this procedure, both with and without success. Lacerations and Injuries to the Brain-substance. These have been already nearly sufficiently alluded to under the term contusion of the brain. They may be divided into those which occur with or without fracture of the cranial bones. The term contusion was first suggested by Dupuytren. The condition comprises all degrees of injury, from the most minute local disturbances to lesions involving the entire hemisphere. The milder forms show a sprinkling of punctate hemorrhages, numerous in the centre of the injured area, the surround- ing tissue taking on a more or less diffused tint, which fades out toward the periphery, discoloration being due to the imbibition of the coloring matter of the blood. In more extensive injuries clots as large as peas or larger are imbedded at various points, each surrounded by its area of discoloration. When foreign bodies have been driven into the brain, the tissue is also discolored, while various foreign materials may be met with. In an instance of great violence there may occur absolute rup- ture of brain-tissue extending from cortex to ventricle. 48 INJURIES AND SURGICAL DISEASES OF THE HEAD. When the body which causes the injury is small the contusion will be found usually close to the site of injury or perhaps opposite to it (contre-coup). The cerebro-spinal fluid is an important agent in the production of disseminated and even distant lesions. When the lateral ventricles are compressed their contained fluid seeks to escape through the Sylvian aqueduct into the fourth ventricle and the central canal of the cord, all of whose walls may be materially injured by this sudden distention. In these locations especially, then, we expect to meet with minute extravasations. They have been seen even as far as the lumbar portions of the cord. The combination of contusion and intrameningeal hemorrhage is most common, and is that portrayed in Plate II. It is the feature of contusion which constitutes the most serious complication and the most serious obstacle to recovery after operation for removal of sub- or extradural clot. Prognosis.—Prognosis depends in large degree upon escape from or occurrence of infection. In infective cases the principal dangers are from blood-pressure and from later oedema or acute softening. Brain lacerations may heal by cicatricial repair, but usually with some perver- sion, at least trifling, of function. The possibility of cystic degeneration of large or small clots is one of very great importance. (See Cystic Softening, p. 392, Volume I.) A blood-clot now within the cranium which fails to resorb is essentially a haematoma, in whose interior soft- ening and conversion into a cyst may easily occur. These cysts make room for themselves at the expense of surrounding brain-tissue, and when located in the motor area give rise to localizing symptoms as well as to epileptic convulsions. They may be often diagnosed with certainty after an accurate history of the case and the study of the phenomena which it presents. As they grow older their walls become firmer, and it is often possible to dissect them out as one removes any other cyst from its surroundings. That foreign bodies may be encapsulated and remain without producing disturb- ance is now well known. As a rule, however, though encapsulated, they produce symptoms like headache, vertigo, etc. Fig. 13. Bullet imbedded in anterior fossa (U. S. Army Med. Museum). In penetrating wounds the canal usually terminates in a blind extremity, although points of knife-blades or other foreign bodies may remain in its depths. It is important to remember that the brain may be penetrated through the orbit or the nose, and that small substances introduced in this way may cause subsequent fatal meningitis. Thus, fragments of glass, umbrella tips, ends of foils, knife- blades, etc. have produced cases whose history is interesting reading, but which cannot be detailed here. Needles have been found in the brain which must have been introduced long before, probably in infancy, and which appear to have caused little or no disturbance. . Symptoms.—The general features of brain lacerations are those of PROLAPSUS AND HERNIA CEREBRI. 49 contusion already alluded to, somewhat exaggerated in many cases. So long as the disturbances are minute, even if multiple, or the foreign body small, compression symptoms are not produced, or at least in very incomplete degree. Minute diagnosis is, of course, impossible. The most essential thing is to decide upon the question of operative inter- ference. In the absence of distinctly localizing symptoms or other external markings, which of themselves would indicate operation, it is usually abstained from. Upon the other hand, a lesion which can be distinctly localized is probably due to extravasation large enough to be quite probably reached by opening the skull; and, unless there be other and sufficient reason to the contrary, this should be done. In many instances, however, contractures or paralyses of muscle- groups occur later, and are followed by spastic conditions which may be permanent. More can be done in these cases by massage, by internal medication, perhaps with external counter-irritation, than by distinctly surgical procedures. Both albuminuria and glycosuria are known to be the result of injuries herein referred to, as well as bulbar paralysis and disturbances of special senses. More immediate dangers after these head injuries are those of broncho-pneumonia or hemorrhagic or oedem- atous infiltration of the lower lobes of the lungs—conditions often spoken of as hypostatic pneumonia, much resembling those produced experimentally in bilateral division of the pneumogastrics. Some of them are produced by paralysis of the glottis, the result of which is incomplete closure, with aspiration of fluids and solids from the mouth whose decomposition sets up an infection within the lungs which is often spoken of as aspiration pneumonia. Some form of pulmonary disturb- ance follows in perhaps one-third of the cases of the injuries above alluded to, and should be guarded against in every possible way. Treatment.—Most important of all is it to emphasize that the safety of these patients depends in large measure upon the treatment primarily received at the hands of the first medical attendant. If this be careful and aseptic, complications may be avoided; if otherwise, infection within the cranium or within the thorax is very likely to cause the patient’s death. Absolute and primary disinfection of all external injuries, no matter what may be considered the condition within the cranium, and rigid care with regard to the feeding of the patient and his general nursing, will never be more life-saving than in these instances. These remarks are made because contusions and the more extensive lacerations are rarely met with in the absence of some scalp wounds or fracture, which of themselves should be treated along lines already clearly indi- cated. When the trephine is not called for on account of external injury, its use should be dictated entirely by what may be judged of the internal conditions and by indications already considered. Prolapsus and Hernia. Cerebri. Escape of brain-matter beyond its normal level is not uncommon in connection with compound fractures or their sequelae. It may be pri- mary, escaping with the blood at the time of the accident, or secondary, occurring during the ensuing days. Any lesion of this kind in which the brain appears or can be handled is entitled to the term prolapsus, in 50 INJURIES AND SURGICAL DISEASES OF THE HEAD. contradistinction to hernia, which implies that, though escaping from the proper cavity, it is nevertheless covered by other textures—e. g. dura or scalp. The protrusion may vary in size from a very small tumor to one the size of a fist. It is always the result of increased intracranial tension, and may be produced by hemorrhage, by serous imbibition, or as the result of brain-abscess. When immediate, it is of the first variety; when later, of the second or third. When abscess is present it usually delays a protrusion, which is produced by degrees. Prolapse occurs for the most part through large openings, such as those made by gunshot wounds, the trephine, etc. Prolapse proper implies laceration of the dura. It pertains obviously to the convexity of the skull, occurring, however, in exceedingly rare cases into the orbit, etc. The prognosis is generally unfavorable. There is always risk of oedema or infection, either of which may prove fatal. Infiltration, gangrene, suppuration, or repair by granulation may so disfigure and disguise the real brain-substance as to lead to error of diagnosis. It by no means follows that every tumor presenting through an opening in the skull is of this character. When gangrene and spontaneous separation occur, spontaneous recovery may follow, the stump being covered by granulations and finally roofed over by connec- tive tissue. Treatment.—Treatment in the primary cases should include the most rigid asepsis with removal of all foreign particles. Localized pressure does some good, especially in those cases where it can be tole- rated. Signs of abscess should always be watched for, and deep explor- ation is often justified or indicated. While excision, cauterization, etc. are often heralded as successful, they are by no means without their dangers. Cases that admit of it should wear a protective shield properly moulded to the part. Skin-transplantation, or even osteoplastic repair of the defect, may give good results in favorable cases. Injuries to Cranial Nerves with or without Lesions of the Cranium. The olfactory nerve is sometimes injured by-penetrating wounds of the frontal region, or, again, by infiltration of fluid along its course through the pores of the lamina cribrosa. In some of these latter cases function returns, after a while. Loss of smell is not necessarily due to injury to this nerve, but may be produced by the plugging of the nostril with blood, etc. The optic nerve may be injured at any point. It has been torn from the globe by external violence; foreign bodies may be imbedded in it, etc. When the lesions occur posterior to the entrance of the central vessels, the ophthalmoscopic picture will be normal, at least for some time, but when anterior to the vessel entrance changes are produced much resembling those of embolism of the central artery. The optic canal is often injured in basal fractures and the optic sheath more or less filled with blood, whose presence is not always easily accounted for. Fragments may be splintered from the canal, and these may injure the nerve. 51 SEPTIC INFECTIONS WITHIN THE CRANIUM. The oculomotor or third nerve may be injured during birth by the pressure of obstetric forceps, as well as by fractures of the orbital roof or by penetrating wounds. Paralysis of the fourth nerve after head injury is very rare. The abducens is paralyzed in some cases of pulsating exophthalmos. Injuries to the fifth nerve are mostly observed in connection with extensive lesions involving as well the other cranial nerves. Anaesthesia of the trigeminal area after head injuries leads to a neuro-paralytic lesion of the eye, and there is reason to think that many cases of unilateral atrophy of the face are due to some injury in the neighborhood of the petro-basilar synchondrosis. The seventh and eighth pairs are more frequently injured—the facial, for instance, by the obstetric forceps during parturition at its exit from the skull, or by various blows from the outside. In basal fractures it alone, or with the auditory nerve, has been paralyzed in numerous instances. When the facial is torn across, as may easily happen during its passage through the petrous bone, paralysis may be immediate, and probably permanent. If improvement or recovery follow, the nerve certainly has not been divided, but the paralysis is probably due to pressure by blood-clot in the Fallopian canal. In other instances where facial paralysis comes on more slowly it is probably due to an ascending neuritis. Disturbances of the auditory nerve have more significance in diagnosis of basal fracture than those of the facial. Hemorrhages into the internal ear, or even fill- ing of the middle ear, may occur without fracture, but the presumption is in favor of such injury. The other cranial nerves have been known to be injured in one way and another, but such injuries are mere surgical curiosities, save in those cases where the lesion is so extensive as to determine a speedy death. Septic Infections within the Cranium. Under the general term septic infection I mean to include— A. Abscess; B. Thrombosis; C. Sinus phlebitis; D. Meningitis; E. Encephalitis ; these being in effect different manifestations of infection, the clinical picture differing according to the tissues and localities involved. For the production of these infectious conditions no special bacteria other than those already alluded to in Chapter III. Yol. I. are comprehended. Their method of activity is there discussed at sufficient length, and we need here only consider the various paths of infection. These may lie along the blood-vessels, the lymph-vessels, nerve-sheaths, and prolongations of the membranous sacs which extend from the cranial cavity proper. There is free communication around the brain-box of all the sinuses or cavities which contain air which have to do with the senses of smell and hearing. There is, furthermore, free communication between the orbit and the interior of the cra- nium. Infection commencing in the nose may spread to the ear by the Eustachian tube, to the frontal and ethmoid sinuses by means of the continuous lining mem- brane, or to the brain proper or its membranes by the lymphatics, whose connec- tion therewith has received ample demonstration. When the middle ear is filled up with granulation-tissue, this will form a most favorable site for the development of micro-organisms. The same is true of the frontal sinus when the infundibulum is partially closed. In both of these cavities, as in the mastoid cells, organisms find a closed incubating chamber most favorably located. The extension of both the subdural and subarachnoid spaces along the optic nerve will easily explain the transmission of infection from the orbit to the brain. It has only been recently recognized that the teeth also constitute paths of infection, and abscess in the brain may be found containing pathogenic organisms normal only in the human mouth. Furthermore, cellulitis in its various expressions may find an easy propagation from the scalp to the membranes, or even to the brain itself. 52 INJURIES AND SURGICAL DISEASES OF TIIE HEAD. If the inflammatory process be slow, we may have localized involvement of the dura with extradural abscess, with perhaps adhesive inflammation, resulting in adhesions with the arachnoid and pia; by virtue of which a general meningitis is guarded against. Adhesions failing or when the infection is widespread, we have invasion of the whole subdural space and general leptomeningitis. Both this, as well as abscess, may result from thrombotic or embolic processes alone, which are then secondary to some similar disturbance elsewhere primary. There are also numerous traumatic conditions predisposing to infection, par- ticularly punctured wounds. Here infective thrombosis in the diploe extends along the perivascular sheaths to the brain. In subperiosteal abscess deep extension is also favored. Punctured fractures, as basal fractures, permit the introduction of infective materal. Even from contusions and injuries which have not produced fractures we may get external abscess, which may later communicate an infection to the interior. The most common of all the paths of infection is afforded by the middle, ear, especially when involved in a chronic suppurative lesion, which is by no means necessarily connected with the patulous tympanic membrane, and which may consequently be undiscovered, though in more or less constant activity. A. Abscess of the Brain.—This may be traumatic or non-traumatic. The former variety is for the most part due to the direct result of injury, infection displaying its consequences promptly or sometimes not until long periods of time have elapsed. The ordinary form occurs within the first two weeks, usually as an acute cortical abscess beneath a more or less compromised membrane, surrounded by a zone of red softening, and this by another of brain oedema. The chronic traumatic abscesses are less often cortical, but usually are deeper. They are usually marked by prolonged suppuration of the external wound, but sometimes occur through some mechanism not yet well understood. Only the chronic abscesses show encapsulation, the capsule partaking of the character of the pyophylactic membrane (see Vol. I. Chapter IX.) elsewhere described. It may cover a long period of time—to my personal know- ledge at least nine years, while others have mentioned twenty and more. The non-traumatic abscesses are for the most part due to middle-ear dis- ease. When the roof of the tympanum breaks down, it is the middle fossa of the skull which is infected ; when the posterior wall, naturally the posterior fossa. The most common results of perforation of the tympanic roof is involvement of the mastoid antrum or the sigmoid groove and sinus. In the former case we get temporo-sphenoidal abscess ; in the latter, cerebellar, if any. Previous to actual perforation there is thinning of bone with thrombosis along the minute veins con- nected with the sinuses. When the dura is exposed by the carious process, granulation-tissue often protects it against further inroads, while masses of the same projecting into the tympanum have been mistaken for prolapse. If the sigmoid groove be the site of the first disturbance, extradural abscess may form between the sinus and the remaining bone, the granulating process then involving the whole bony groove. Its later consequence is sinus phlebitis, sinus thrombosis, or intradural infection. If there be adhesion between the dura and the cortex, we get actual brain ulceration without formation of a true abscess; but if once the perivascular sheaths have carried infection to the substance of the brain, there is a rapid purulent disintegration of the same, and formation of a true subpial or deep abscess, which latter is in effect a purulent en- SEPTIC INFECTIONS WITIIIN TIIE CRANIUM. 53 cephalitis. Macewen has shown how important it is not merely to evacuate such abscesses, but to eradicate the path of infection from the point of origin, which is rarely easy. Extradural pus may escape into the mastoid cells by erosion of their inner walls. Such pus may escape suddenly, and serious symptoms thus be mitigated. Even abscess of the bone may thus empty itself by the process of adhesion and pointing toward the surface, but such a thing is most rare. Pus from the mastoid cells may perforate the tempo ro- maxillary joint or escape along the digastric groove and form deep cer- vical abscesses. Once the arachnoidal tissue be involved, both subdural and sub- arachnoidal spaces participate in the infection, and the brain floats upon a pus-bed rather than a water-bed. Leptomeningitis under these circum- stances becomes quickly diffused and fatal. Serous fluid may accumulate so quickly as to produce death by mere obstruction to the cerebral blood-vessels, while distention of the ventricles and an acute infectious internal hydrocephalus is possible. Leptomeningitis may be propagated wherever anatomical paths may carry it, even to the cauda equina and along the spinal nerve-sheaths. The pus within cerebral abscesses is often discolored, sometimes offensive. A greenish color is usually imparted by the bacillus pyocy- aneus, while the offensive odor comes mostly from the bacillus coli. Around every such abscess is a zone of actively inflamed cerebral tissue. If within this zone a pyophylactic membrane may be produced by con- densation, the abscess may become encapsulated and life be prolonged. When a capsule fails to form, the process being too acute or rapid, death is the speedy termination of such a case. These abscesses are for the most part single, but may be multiple. There is also a metastatic expression of abscess-formation, seen in typical cases of pyaemia where numerous miliary abscesses are found within the brain. Pressure- symptoms are less likely from abscess than from a tumor of the same bulk, while there is much greater liability to oedema and sudden infec- tion. Gradually extending paralysis implies pathological activity around the abscess. Large collections of pus are often met with in the least vital parts of the brain, as in the frontal or temporo-sphenoidal lobes. Symptoms of Brain-abscess.—Aside from causal indications (e. g. injury to the head, middle-ear disease, recent operations upon the air- containing cavities, etc.), the first symptoms may be slight. They con- sist usually of headache, often ascribed to cold or trifling injury, becom- ing exaggerated, rarely definitely located, radiating widely. In time it is spoken of as “ excruciating,” and may be continuous or intermittent. Vomiting is not infrequent, rarely accompanied by nausea. Chills come on early in the history of the case, varying in intensity, duration, and fre- quency. The more frequent, the more likely is it that the abscess results from some general infection. Temperature is seldom much elevated ; it is often subnormal. When exalted, it is in proportion to the degree of meningeal involvement. If pressure-symptoms become marked, we get the usual slow pulse due to increased tension. After evacuation of pus pressure-symptoms may subside, but temperature rise. Such discharge from the middle ear as may have been previously noted usually dimin- 54 INJURIES AND SURGICAL DISEASES OF THE HEAD. ishes. A history of cessation of discharge and of increased pain and fever occurring at irregular intervals is very characteristic. These patients seldom come under the surgeon’s notice until the con- dition is evidently most serious. If they are still conscious, pain is the dominating complaint. This may he aggravated by percussion over the affected region. Rigidity of the sterno-mastoid on the affected side is a sign of lesion of the sigmoid sinus. Pain elicited by deep pressure in the posterior cervical triangle is also significant. There is mental hebe- tude, progressive failure of mental and physical power as the stupor increases, or coma becomes marked. Abscesi$ may be often distinguished from infectious thrombosis, since in the latter respirations are quickened and vomiting occurs when the patient is in the upright position. Vomiting accompanied by cephalalgia is always indicative of intracra- nial mischief. If it be a special feature throughout the case, it may indicate cerebellar lesion. Convulsions are also frequent, but rarely dis- tinctive. They are the result, for the most part, of secondary irritation of motor areas. Paralysis is the consequence of destructive rather than of irritative lesions. Much of value can be learned from a careful examination of the ear, and here the careful use of a probe will give much information. Localizing symptoms are only occasional in connection with cerebral abscess, because the majority of these lesions are located without the motor area. Pupil- lary alterations are indefinite. As an abscess enlarges the size of the pupil may increase. Infective thrombosis rarely affects the pupils, save that when located in the cavernous sinus it may produce ptosis. In teviporo-sphenoidal abscess pain is usually localized at or near the ear upon the same side. As the motor area becomes involved we have the gradual development of distinctly localizing phenomena, referred to the opposite side. Facial paralysis is common in advanced destructive lesions in the mastoid and tympanum. When produced by cortical lesion it is rarely so pronounced as when by direct paralysis of the nerve. In frontal abscess there are few, if any, localizing phenomena. Abscess in the parietal region is most commonly of traumatic origin, and is to be suspected in accordance with external surface markings. Occipital abscess is exceedingly rare; cerebellar abscess furnishes few localizing symptoms. Its most prominent clinical features are retraction of the head and neck; slow, feeble pulse and respiration; subnormal temperature; vio- lent yawning; rigidity of the masseters; slow speech ; optic neuritis; vertigo and vomiting. If accompanied by thrombosis, there is pain and pressure in the upper part of the neck. In all of these cases when abscess is near the surface there is more or less leptomeningitis, which becomes diffuse at once when the abscess bursts. If meningitis be present, we have high temperature without marked remissions, rapid pulse, and general irritability, rapidity of pulse indicating predominance of lepto- meningitis over encephalitis, since the more marked the latter the slower the pulse. As distinguished from sinus thrombosis, we have, in the latter, high temperature with marked remission, rapid and wreak pulse, frequent chills, profuse sweats, and often symptoms of pulmonary infarct, or diarrhoea, with cervical and submastoid tenderness and involvement along the jugular vein upon the affected side. If all three conditions be associated, the symptoms of thrombosis usually prevail, though we may get retraction of the head due to basilar meningitis. As between tumor and abscess we have in the former absence of explanation of infection, slow progress of symp- toms, more definite localizing phenomena, progressive involvement of nerves, pro- nounced optic neuritis, absence of chill, and alternating periods of mitigation of symptoms. Temperature and pulse afford little help, save that subnormal tempera- ture points rather to abscess. Prognosis.—From every direction come statements that the tendency of cerebral abscess is invariably toward fatality. No matter what the SEPTIC INFECTIONS WITHIN THE CRANIUM 55 cause, unless relief be promptly afforded death is the sure result. Of the acute cases, those not promptly operated usually die within a few weeks; the more chronic or prolonged cases unfortunately rarely come under surgical treatment. Most of those which do are the result of dis- ease in or about the middle ear. Were it possible to diagnose an attack of these abscesses early, prognosis would be much more favorable. When seen before necessarily fatal complications have arisen, in in- stances where the position can be reasonably well determined, surgical attack is likely to give good results. After proper evacuation even com- plete mental and bodily recovery is possible. Anchoring of the brain by adhesions may leave a train of disquieting symptoms, which, however, are not so bad as fatality. One must never forget that abscesses may remain for a long time encysted, and yet be a fruitful source of danger. Multiple abscesses may complicate both the diagnosis and the treatment and produce a condition beyond help. The operative treatment of these cases will be discussed by itself. B. Sinus Thrombosis.—The sinuses are predisposed to thrombosis by virtue of their size, inflexibility, shape, and the fact that they are not emptied during respiration; all of which tend to retard blood-flow. If to these be added defect in the blood-supplv, then everything predisposes toward marasmic thrombosis. This occurs much less frequently than the infective form, is mostly confined to the longitudinal sinus, is noted mainly at the two extremes of life, and is often seen in cases of death following exhausting diarrhoea in children. In the marasmic form, the clots are dense, firm, stratified, and non-adherent; they very rarely occupy the whole calibre. In the old cases the clots may be tunnelled sufficiently to permit re-establishment of circulation. Their principal evil conse- quences are oedema of the frontal lobes and sero-sanguineous effusion into the ventricles or orbits—in the latter case producing exophthalmos. Sometimes epistaxis is produced. Strabismus, tremor, muscle-rigidity or contractures are more often seen conjoined, especially in children, with convulsions, sometimes unilateral, and choked disk. The diagnosis in adults is difficult, but in children, when convulsions occur after exhausting illness with the signs just noted, marasmic throm- bosis may ordinarily be diagnosticated. Infective thrombosis, the other variety, is due exclusively to the inva- sion of pyogenic organisms. It is met with mostly in the basal sinuses ; its origin is local, and it is always secondary to some external infection. Its most frequent cause is middle-ear disease ; consequently, the sigmoid sinus is the one most often involved. It may follow carbuncle, erysip- elas, or cellulitis of the external parts, or nasal ulceration, as well as dental caries, suppuration of the tonsils, etc. Infection may be propa- gated by tissue-continuity or through the circulation. Clots form for the most part rapidly, completely occlude and quickly adhere to the sinus-walls; soon they begin to disintegrate, pus is formed, and the resultant fluid is a mixture of blood-elements and pus swarming with bacteria and tending constantly to enlarge the limits of the lesion. The clot frequently extends into the internal jugular, with production of local lesions. Outside, the smooth venous walls have less resistance, and there is more opportunity for dislodgement of clot. Purulent fluid often collects between the sinus and the surrounding bone and may escape by the mastoid vein. Its significance upon the exterior should never be minimized. So, also, it may extend along the posterior condyloid foramen and 56 INJURIES AND SURGICAL DISEASES OF TIIE HEAD. produce deep cervical abscess. This pathological activity, if not too rapid, tends to the formation of granulation-tissue around the sinus-walls, which will extend into the bone as into the lumen of a vessel. It may act as a barrier and later organize, or it may itself rapidly break down. The terminal limits of most of these thrombi are protective. Thus, a cord-like mass in the internal jugular, beneath the sterno-mastoid, helps to protect against pulmonary infarct. Symptoms.—Infective thrombosis presents few distinctive symptoms. Local ischaemia, perversion of function, extracranial oedema are too vague. Headache is nearly always constant, and vomiting is frequent; temperature runs high with marked remissions; the pulse is small and rapid, and remains so even under an anaesthetic. Chills are frequent, are of the pyaemic type, and are followed by copious sweats. Should pulmonary infarction occur, we will have the typical thoracic signs, although at first physical examination may give negative results. Later, however, we get prune-juice expectoration, putrid sputum, etc. Cere- bral function is disturbed late, rather than early. The duration of the disease ordinarily is from two to four weeks. Should meningitis com- plicate the case, there is more violent headache, persistent high temper- ature, great excitement, muscle-spasm, strabismus, delirium, and coma; if the sigmoid sinus be involved, there is usually retraction of the head. Should leptomeningitis extend down the spine, girdle pains will be com- plained of. We may also have exophthalmos on one side or both, with conjunctival injec- tion, oedema of the lids, and disturbances of vision, due to thrombosis of the cavernous sinus and stasis in the ophthalmic vein. In thrombosis of one trans- verse sinus only the internal jugular on that side will carry less blood. So long as that on the other side is free, it will take that which cannot pass through the obstructed one. Consequently, the jugular on the other side will carry more. But if the contained clot extend so far that direct communication with the internal jugular is interfered with, then the internal jugular of the affected side will be almost empty, while the external of the same side will be the more distended. When the eye is protruded and the frontal vein distended, it is evident that the cavernous sinus on that side is involved. If the superficial veins of the scalp be distended, it is the superior longitudinal sinus which is at fault. When the veins of the mastoid region are involved, we may locate the thrombus in the transverse sinus; when there are no localizing symptoms, we can only say in a general way that thrombosis has occurred. Prognosis is always unfavorable, though recovery is not impossible. The therapeutics are in the main prophylactic. By actual physiological rest the possibility of pulmonary complications can be diminished. The treatment, aside from this, is purely operative, and will be discussed elsewhere. C. Sinus Phlebitis.—This may be the result— (a) Of thrombosis; or, (b) The continuation of suppurative processes from neighboring tissues. Infective thrombi produce sinus phlebitis by direct extension from within, as do surrounding suppurative foci from without. Acute sup- purations often follow vessels and nerves, and work their way along the connective tissues surrounding them, and thus penetrate from the dura into the sinus ; but for the most part the veins which empty into a sinus are directly responsible for its. infection. External lesions as well as internal furnish such infection by means of the wonderfully free venous anastomosis. SEPTIC INFECTIONS WITHIN TIIE CRANIUM. 57 In sinus phlebitis the sinus-walls are thickened and infiltrated, while its cavity is filled with breaking-down clot. The veins of the cortex and its membranes are overfilled, and extravasations often complicate these cases. In fact, with sinus phlebitis we often find pachymeningitis and leptomeningitis, and even brain-abscess. Symptoms.—These are seldom absolutely diagnostic. Sinus phle- bitis is often accompanied by meningitis, even encephalitis. The first symptom is usually severe headache, often localized, made worse by pressure. Anorexia, with early mental disturbance and often delirium, follows, with vomiting, restlessness, and mania, changing to stupor and coma. Rigidity or spasm of cervical muscles, or of those of the extrem- ities, followed by paralyses, is often seen. Evidences of irritation of special nerves, particularly the oculo-motor or the vagus, are not rare. When pysemic symptoms occur they are vague and are most conspicuous in the lungs and liver. Taken in conjunction with aggravating brain- symptoms, they make prognosis most unfavorable. Symptoms will in large measure depend upon the sinus most involved. They are most characteristic if this be the cavernous sinus. Here we have disturbances in the eye on the same side, congestion of orbital veins, pain and photophobia, and, later, cloudiness of the cornea and cedema with exophthalmos. Finally, the pupil becomes paralyzed and dilated, the cornea loses its polish, the upper lid cannot be raised, and, if the case persist long enough, the cornea ulcerates. Along with these local evidences there will be complaint of frontal pain, usually with paralysis of the hypoglossal nerve and consequent thickness of speech. When the transverse sinus is involved, we have, first, vagus irritation, then paralysis with paralytic sequences in the muscles of the jaw, the tongue, palate, pharynx, etc. Diaphrag- matic motions are interfered with and the character of the respiration altered. As the trouble extends to the internal jugular, we have further paralysis of accom- panying nerves, especially of the hypoglossal. As the irritation extends down the vein, we will have tenderness, rigidity, and often swelling. The local signs and symptoms vary obviously as the lesion extends from one sinus to the other, since when one cavernous sinus is involved the trouble nearly always extends to the other, and local symptoms are repeated upon the opposite side. Diagnosis.—Primary symptoms are those common to all of the intracranial infections. In the presence of pygemic features symptoms of local involvement, swelling of joints, etc., one can ordinarily elim- inate the pure type of meningitis. Should there be evident reason for deep infection, diagnosis is also simplified. Oculo-motor paralysis, ptosis, pupillary alterations, etc., occurring early, are of great importance. Eye- symptoms point primarily to the cavernous sinus, while lesions of the vagus or hypoglossal or glossopharyngeal nerves point to the transverse sinus, as do pain or tenderness over the mastoid or down the neck. D. Meningitis.—The dura has a duplicate anatomical character. Its outer surface, having the structure of periosteum, functionates as such; its inner surface, being lined with endothelium, partakes of the nature of a true serous membrane. When the former texture is mainly at fault, we have pachymeningitis externa, or endocranitis, which is rarely primary, but usually a propagated lesion met with after injury or external infection. It may lead to infiltration with purulent products, and, if speedy exit for pus be not provided, to involvement of the pia within. Extradural suppuration without external injury is very rare, but should there have been a subdural hemorrhage with external lesion, the blood-clot may become infected and break down. Pachymeningitis 58 INJURIES AND SURGICAL DISEASES OF THE HEAD. externa is most common after chronic lesions of the cranial bones—i. e. caries and necrosis—and is scarcely to be separated from them. Symp- toms are not characteristic and often not distinguishable. When chronic, there will be local tenderness, evidence of the presence of pus, perhaps with focal symptoms. The treatment is always surgical, save possibly in certain cases due to syphilis, where delay may be justifiable for the purpose of testing the action of antispecific drugs. Pachymeningitis interna is often confounded with chronic hydro- cephalus. It is frequently the occasion of a firm membranous exudate upon the internal surface of the dura, which forms in time a new mem- brane rich in small and extremely friable vessels, from which hemor- rhages easily occur, thus giving rise to the condition of pachymeningitis hsemorrhagica. Trifling hemorrhages will produce little or no disturb- ance ; when of greater extent they may give rise to localizing brain- symptoms. These extravasations may absorb or undergo fluidification— i. e. produce localized or cystic collections of fluid. The condition some- times occurs after other acute infections, especially pneumonia, pleurisy, typhoid, whooping cough, etc. Recovery is possible, but usually at the expense of adhesions, which lead to subsequent complications. Treatment must be in a large degree surgical, since little short of eradication will bring about the desired result. The symptoms of pachymeningitis hcemorrhagica are headache, which will increase in intensity with every new escape of blood, usually local- ized in the vertex, with more or less paralysis following each new extravasation. The final result may be atrophy, even extensive. Absence of disturbance in the cranial nerves points to lesions in the convexity rather than basal or ventricular. In chronic cases we have optic neuritis, and toward the end coma, coming on for the most part slowly. Dennis has recommended trephining under these circumstances, and has practised it with great benefit. Leptomeningitis.—This term refers to inflammation (i. e. infection) of the pia mater, in whose texture we encounter tissue quite different from that composing the dura, and in which, when inflamed, distinction as between arachnoid and pia has disappeared. Leptomeningitis suppura- tiva is an exceedingly common expression of intracranial infection, and may result not merely by extension, but as a primary infection. When begun, it spreads most rapidly, the fluid contained within the meningeal cavities, mixed with pyogenic agents, helping to disseminate the active agents to the ultimate limits of the membranous involvement. Conse- quently, basilar meningitis usually extends down the spinal canal. Next to injury, the most frequent cause is middle-ear disease with its infectious complications and extensions. Next to this come sinus phlebitis and endocranitis. Infection from the teeth and the nasal cavity may occur. It is also known to result from panophthalmitis: in traumatic cases, when primary, it sets in early, even from four to thirty-six hours after injury. So rich is the pia in loose connective tissue that even from the outside the inflammation may assume the phlegmonous type. Thecere- bro-spinal fluid, as well as that of the ventricles, becomes cloudy, con- tains numerous flocculi, and is often blood-stained. Symptoms.—When the disease is limited to the vertex and follows SEPTIC INFECTIONS WITHIN THE CRANIUM. 59 several days after injury, it begins usually with chills and malaise, with increasing temperature; after which the symptoms assume the pysemic type, distinguished from true pyaemia by their comparatively early onset. The pulse becomes frequent, first full, and then small; patients are dis- turbed, restless, or uncontrollable, complain of headache, moan, grate the teeth, become delirious, with glistening eyes and congested face. After a while delirium subsides into stupor and restlessness into insensi- bility. The pupils contract and remain inactive to light. Paralyses, cramps, etc. are not infrequently met with. Traumatic basilar leptomen- ingitis occurs often with fracture of the base. Signs and symptoms are less distinctive here ; paralyses occur more easily and are less distinctive, save those which involve the special cranial nerves. When ptosis occurs with dilatation of the pupils, glossopharyngeal paralysis, etc., we should be quick to suspect extension of the process along the brain. Cramp or stiffness of cervical muscles means the same thing, and is a sign of very grave import; it may even be considered pathognomonic. Albuminuria is frequent, with marked increase of phosphates in the urine. In the non-traumatic cases the symptoms of leptomeningitis are those of increasing brain-pressure and temperature. The disease usually com- mences with headache followed by vertigo, hypersesthesia, restlessness, delirium, insomnia followed by somnolence, muscle-spasm, paralyses, coma, and death. If the disease extend from the middle ear, we fre- quently have facial paralysis before the meningeal symptoms appear. The type of fever is one of gradual increase, though before death temperature often falls even below the normal. Pathognomonic fever should not be mistaken for the elevation of temperature which often accompanies absorption of intracranial hemorrhages. In these latter cases temperature may amount to 39° C., but if rising higher than this, meningeal complications should be suspected. Diagnosis as between sinus phlebitis and leptomeningitis depends for the most part upon the recognition of pysemic symptoms. When the latter are entirely wanting, we may at least say that the predomina- ting symptoms of sinus phlebitis are absent. Prognosis is almost always bad. Many cases end in forty-eight hours; others may live for two weeks or more. Treatment seems almost futile, though one should endeavor by ener- getic purgation, venesection, etc. to do what he can. The only prospect or hope comes from the possibility of relieving the compression from effusion of purulent fluid, and of irrigating and draining what is now an enlarged abscess-cavity. Since now we do not hesitate to open and wash out other serous cavities when thus affected—e. g. peritoneum, pericar- dium, joints, pleura, etc.—we should no longer hesitate to open the dura and wash out the subdural space, even though this necessitate more than one trephine opening. The measure was suggested by S. W. Gross in 1873, when he reported cases thus treated with success, and has since been practised by other surgeons, among them by Souchon, who has advised multiple puncture with the small drill and irrigation and disin- fection through numerous small openings. Of 11 cases collected by Gross more than twenty-five years ago, 45 per cent, recovered. E. Encephalitis.—The etiology of this condition is practically that of leptomeningitis. It may proceed from sinus phlebitis or from the 60 INJURIES AND SURGICAL DISEASES OF THE HEAD. veins emptying into the sinus, infection travelling backward rather than forward. In many cases the primary infection occurs from without, as in gunshot fractures, etc. It is also transmitted along the lymphatic channels, since I have operated on abscess in the frontal lobe following intranasal operation. It assumes practically always the suppurative type, and may run either an acute or a chronic course. When acute, the lesion is usually limited in area, and the result is an acute abscess with irregular boundaries. Symptoms.—These will depend largely upon the portion of the brain involved and the acuteness of the process. Symptoms may even be almost lacking. When present, they are mainly those of brain- pressure, often with localizing phenomena. Convulsions with loss of consciousness, vomiting, slowing of the pulse, stertorous breathing, almost always followr a serious form of diffuse encephalitis. When pysemic symptoms complicate the case, they point toward a sinus phle- bitis as the origin of the encephalitis. These collections of pus within the brain may long lie latent or encapsulated, and then be suddenly aroused into acute activity, proving fatal by an acute dissemination with serous oedema; all of which will be evidenced by symptoms as given above. When active trouble is aroused, it is ushered in by chills, after which compression symptoms occur very promptly. Diagnosis must be made largely upon the history. Prognosis is always unfavorable, and treatment will depend entirely upon what can be inferred as to the nature and location of the primary cause. In most cases by the time a diagnosis is fairly arrived at it is too late to do anything. Operative Treatment of Intracranial Suppurations. In dealing with pus the surgeon can never follow a safer rule than to go according to this dictum : i. e. that pus left alone is a greater source of danger than the surgeon’s knife judiciously used. Consequently, ubi pus, ibi evaeua, applies to intracranial collections as well as others. For its detection and evacuation, operations are now regarded as not merely justifiable, but indicated whenever there is presumption of its presence. Discussion now hinges entirely upon the wisdom of explora- tion when absolutely no diagnosis can be made. But when we re- member the inevitably fatal tendency of these abscesses and the rela- tively exceedingly small danger of exploration, we may feel that there is at least no part of the cerebral cortex where pus may accumulate where it may not also be attacked with propriety. Save where an open- ing already exists, trephining is a necessary preliminary. Among other indications is spontaneous escape of pus through previous opening or any of the natural outlets of the cranium, with or without localizing phe- nomena. Further indications are those pertaining to the bone—i. e. loos- ening of pericranium; or to the scalp—i. e. oedema, puffy tumor, etc.; and certain other indications are those of a more general character, chills, pyrexia, etc. When the dura is exposed, much can be judged of by the existing brain tension, it Being now well established that brain pulsation is often characterized by the presence of pus beneath the dura. The most feasible method for detection of subdural or deep collections OPERATIVE TREATMENT OF INTRACRANIAL SUPPURATIONS. 61 is by the use of the aspirating needle—a method now generally in vogue and everywhere accepted. In most of the suppurations connected with middle-ear disease will come up the question whether to open the mastoid antrum, the mastoid cells, or the brain-cavity proper. Indications for the first of these are —history of repeated mastoid swellings and tenderness, acute inflam- mations, with soreness or retention of pus in the region of the mastoid, purulent otorrhoea, with beginning symptoms of intracranial mischief, or persistent otorrhoea with offensive discharge, which may long exist without mastoid swelling. The mastoid may be attacked through the suprameatal triangle of Macewen, formed by the posterior zygomatic root and the upper and posterior segments of the external osseous meatus. After opening it with revolving burr or with the chisel, the surgeon must determine the position of its communication with the middle ear and that of the facial canal, the occurrence of facial twitch- ings often announcing the proximity of the surgeon’s instruments to the facial nerve. The middle ear may be opened by extension of the burr- ing process along the outer wall of the antrum to the junction of its roof. Through this opening the malleus and incus may be removed, and should be if diseased; the stapes should be left if possible. Temporo-sphenoidal abscess will often be indicated by the escape of pus through the dura above the roof of the tympanum. It may per- haps be evacuated by enlarging this approach to it, though ordinarily it would be much better to trephine above the ear and remove all the sloughs of brain-tissue. If the mastoid be also involved, the incision for opening the antrum may be extended upward two inches, and the centre pin of the trephine placed three-quarters of an inch above the posterior root of the zygoma. After exposing the dura its appearance should be noted. If it be normal, the course of the pial vessels may be discovered through it. Here, again, the use of the aspirating needle will be most serviceable. Abscess once discovered should be freely opened, diploe removed, and the cavity carefully irrigated. After thorough cleansing, drainage-tubes are of little, if any, use. Gauze packing is by all means the most serviceable. This would necessitate the employment of secondary sutures, or perhaps the leaving of the external wound open from the fundus in order to permit removal of the gauze. In operating upon the sinuses it is best to amply expose the sigmoid sinus, the incision for this purpose extending from the tip of the mastoid to the posterior root of the zygoma. From the posterior extremity of the parieto-mastoid suture a line drawn to the tip of the mastoid overlies the course of the sinus. Opening should be made on the level of the bony meatus. The overlying bone varying much in thickness, the surgeon should proceed with great caution. In the course of operations necessitated by middle-ear disease this sinus is usually exposed, and the antrum has been opened when sufficient reason for the condition is not therein discovered. After exposing the posterior wall of the antrum the bone is opened behind it for half an inch. If in the sigmoid groove granulation-tissue or pus be found, the surgeon should again proceed with great caution. He should expose much more of the sinus-wall and remove all diseased bone in the locality. Every- thing outside of the sinus should also be disinfected before it is opened. After incising it and cleaning out its purulent contents it should be packed with gauze. Hemorrhage is practically always under control by tamponing with gauze. Should the internal jugular vein be felt filled with thrombus or distended, it should be exposed in the neck below the contained clot, ligated, and either split 62 INJURIES AND SURGICAL DISEASES OF THE HEAD. open or irrigated through, so that communication is free between it below and the sinus above. When one can foresee that this may be necessary, it is wise to operate upon the vein first. Operation for relief of purulent meningitis has already been suggested. In the absence of definite indications or of opening, the best point for operation is that at which the meningeal cavity may be properly drained. Opening should be, accord- ingly, made below the superior curved line of the occiput or just above the supe- rior border of the posterior part of the zygoma. It may also be well to open well down in the cervical region. The arachnoid space must also be opened. Souchon’s method of exploration with the ordinary bone-drill, whose point is carefully guarded, and the employment of numerous openings with exploration by the fine aspirating needle, may be put in practice when indicated. Cephalocele. The term cephalocele is applied to tumor of the endocranium pre- senting through defects in the cranial bones, of essentially congenital origin, and containing more or less of intracranial contents. It com- prises— A. Meningocele ; which means a tumor consisting of a membranous protrusion and containing cerebro-spinal fluid ; and, B. Encephalocele ; referring to tumors which contain also more or less of actual brain-substance. Such tumors of non-traumatic origin can only be explained by the existence of congenital defects which permit the escape of that which the normal bone retains within normal limits. In most instances the defect is in the middle line, at either one or the other extremity of the skull. In some instances the arches of the atlas, or even of other cervical vertebrae, are lacking. The most common cephaloceles are the occipital, which are known as inferior when below the occipital spine, or Fig. 14. Defeet in cranium permitting sincipital cephalocele (Bruns). superior when above it. Those appearing anteriorly are known as “sincipital,” and are met with most often at the root of the nose, where they may communicate with the orbit or the nasal cavity. Other and irregular forms are laterally or unsymmetrically located. Thus, we may have naso-l'rontal, naso-ethmoidal, etc. Still another group of cephaloceles escape through fissures or defects at the base of the skull, and, sinking between the ethmoid and sphenoid, present in the naso- CEPHALOCELE. 63 pharynx. Thus we may have naso-pharyngeal, spheno-pharyngeal, spheno-orbital and spheno-maxillary cephaloceles. These tumors are for the most part single, and vary in size within wide limits. For the most part they have an even shape and surface, yet are occasionally divided by folds or constrictions. Many of them have a pedicle much smaller than the tumor itself; others are spread bodily upon the skull. The overlying integument may be very thin, reddened, and vascular, even to such an extent that the tumors are mistaken for angeiomata, or it may be so metamorphosed and thickened as to divert suspicion of their actual character, even to imitate lipomata. Cephaloceles have an elastic feeling, many of them an exquisite fluc- tuation. Sometimes by touch alone we recognize both their fluid and Fig. 15. Occipital cephalocele (original). solid contents. A meningocele with thin walls is translucent. By pres- sure they can be reduced in size, such pressure producing usually brain- symptoms, often paralysis or convulsions. Many children thus affected cannot lie upon the tumor without becoming restless. When the little patients cry or make any violent straining efforts, the tumor becomes larger and its covering more vascular, while during qniet sleep it is usually reduced in size or tension. Fig. 16. Sincipital meningocele (original), A large proportion of patients with these congenital defects die shortly after birth. The tumor, when large, may be ruptured during delivery. Occasionally the sac ruptures spontaneously, which accident is usually 64 INJURIES AND SURGICAL DISEASES OF THE HEAD. followed by purulent meningitis from infection, though it may possibly lead to spontaneous recovery. The principal danger always is of such accident. The encephaloceles are divided into the cenencephaloceles, contain- ing solid brain substance, and hy dr encephaloceles, consisting of the pro- trusion of a dilated brain-cavity—i. e. a thin area of brain enclosing fluid communicating with one of the ventricles. Most of the large tumors pertain to the latter class. The more brain material such a tumor con- tains the more does it pulsate, especially if the patient cry or strain ; the smaller, too, is the skull—i. e. the greater the tendency toward micro- cephalus. As between the different forms of cephaloceles, diagnosis is usually not very difficult. Pure meningoceles are most common in the occipital region; they are translucent, are easily reduced in size by pressure, and are readily emptied by aseptic puncture. The hydrencephaloceles form large fluctuating tumors, often somewhat translucent, symmetrically developed, for the most part occipital in location, not reducible, and but slightly influenced by full expiration. They are most common in con- nection with deformed skulls. The cenencephaloceles are probably the only variety which persists to adult life. They are, for the most part, anterior; may have thick walls; are only partly reduced in size by punc- ture ; pulsate with violent exertion ; diminish during sleep; and are only slightly reducible. Treatment.—Treatment should, first of all, be protective, by a shield of some device held in place by a suitable bandage or dressing. Compression, with or without puncture, has given the most generally satisfactory results, but not much should be expected from any method or combination. Most of the cases are such that extirpation woidd seem applicable, but the impossibility of absolute asepsis in young infants and the liability to fatal shock preclude most of these attempts. In some instances ligature of a meningocele has been successfully applied. In time, injections, as recommended in spina bifida (which see), may also be resorted to. Operation may be attempted in young children with sincip- ital encephalocele. Plastic operations may be resorted to, or plastic manoeuvres combined with extirpation. It may be possible by the inser- tion of a celluloid plate to atone for a small defect in the skull after ex- tirpation of a tumor of this kind. I have successfully practised this method in spina bifida. Hydrocephalus. This term is applied to abnormal collections of cerebro-spinal fluid within the cranial cavity. We speak of— A. Hydrocephalus ventriculorum or internus, when the fluid is confined to the dilated ventricles of the brain; or of— B. Hydrocephalus mening-eus or externus, when the fluid collects between the brain and the dura. The former condition is much the more common. The cause of hydrocephalus in the young .is essentially congenital, and inseparable from imperfect development within the cranium. The forms are occa- sionally combined. At the time of commencing trouble the skull may HYDROCEPHAL US. 65 be of natural size, but yields to the accumulation of fluid within, until it attains relatively enormous dimensions. Most children thus affected die early, some shortly after birth. It is most common in rachitic children. Hydrocephalus developing in the adult is the result almost solely of atro- phy of the brain. Pachymeningitis interna (see pp. 58 and 66) may also produce subdural exudate leading to hydrocephalus externus. Encapsu- lated collections of cerebro-spinal fluid due to pachymeningitis interna are known as hygromata of the dura. A ventricular form of hydro- cephalus may also result from meningitis and tubercular disease. The condition is essentially chronic, the fluid collecting in the dilated lateral ventricles, though the third or fourth are sometimes also distended: 4000 c.c. of cerebro-spinal fluid have been found in more than one instance. As the result of the presence of the fluid there is atrophy of brain, with arrest of development, to such an extent even that the hemi- spheres are changed into great sacs, being merely spread out upon the outer wall of cystic cavities ; all the surface markings are lost, and gray and white substance are scarcely to be differentiated. For the cranium itself the bones of the vertex separate, and instead of sutures we have a tightly-stretched membrane. There is also con- genital or acquired aplasia—i. e. absolute defect of bone between dura and pericranium. All these changes give to hydrocephalic heads a dis- tinctive appearance. Other developmental defects—hare-lip, club-foot, etc.—are common in these patients. Many infants thus affected die dur- ing delivery unless skilful help be at hand. The resulting disproportion between the enlarged head and the small face is most distinctive. Chil- dren in this condition suffer from disturbed digestion, are emaciated, with rachitic curvatures of the long bones; special senses are seldom devel- oped perfectly; strabismus and nystagmus are frequent, while cramps, stupor, etc. are by no means infrequent. Prognosis.—While spontaneous recovery is possible, as already stated, the tendency is always toward fatality. Treatment.—Operative treatment consists either of compression of the enlarging skull by bandages or their equivalent, or the removal of fluid by aspiration, with or without permanent drainage. Compression offers very little prospect of success. Moreover, there is always danger of pressure-sores or even gangrene. Tapping for hydrocephalus is an old operation long discontinued, but recently revived. The establish- ment of permanent drainage is a recent suggestion. When effusion has been rapid, puncture may be resorted to, but in the most chronic cases drainage seems to be the only promising measure. This, however, is made of extreme hazard by the impracticability, almost the impossibility, of maintaining asepsis, though not per se a dangerous operation. In puncturing or draining it is wise to avoid the motor zone and the neigh- borhood of the principal arteries. Perhaps the most serviceable point at which to trephine, preparatory to puncture or drainage, is about 3 cm. behind the external auditory meatus and the same distance above the base-line of the skull. By directing the puncturing instrument to a point on the opposite side, 6 cm. above the meatus, the lateral ventricle will be entered. (The same direction may be of service in opening an abscess in the temporo-sphenoidal lobe.) While the results of this method have been so far very discouraging, it is, nevertheless, the best 66 INJURIES AND SURGICAL DISEASES OF THE HEAD. which presents, save in certain instances where we tap the cerebro-spinal canal at its lower extremity. Lumbar puncture is a suggestion of Quincke, and is made between the third and fourth lumbar vertebrae, the patient’s body being bent forward while it is made. Puncture here may be temporary or permanent drainage may be resorted to. It is a safer procedure than cranial puncture, is applicable both for diagnostic purposes and treatment, and is more likely to give good results. The Cerebral Membranes. The purpose of the dura is to serve as an internal periosteum and as a distinct covering for the brain. It has not only a duplicate purpose, but a duplicate ana- tomical character, its inner surface being lined with endothelium, while its outer surface is densely fibrous. Accordingly, we may have pachymeningitis externa and interna. The external variety is usually the result of extension of trouble from the overlying bone—i. e. from caries and necrosis—as the result of which the mem- brane thickens and its outer surface becomes covered with granulations, while pus may form between it and the bone, and thus be for a long time shut off from access to parts within. Such collections are known as extradural abscesses. Their symptoms are not characteristic, but will include local tenderness, febrile symp- toms, and perhaps focal symptoms. Their treatment is that necessitated by the overlying lesions. Pachymeningitis interna is often confounded with chronic hydro- cephalus externus, to which it may lead. It is characterized by a mem- branous exudate, at first separable from the dura, to which new layers may be added, which becomes richly vascularized and viable, producing a condition in which hemorrhages, minute or serious, are frequent. When a small hemorrhage occurs between the membrane proper and this adventitious structure, we have a condition often spoken of as haema- toma of the dura, sometimes giving rise to localizing brain-symptoms. These extravasations may absorb or undergo fluidification or cystic degeneration, producing the so-called hygromata of the dura. These lesions occur for the most part upon the convexity rather than at the base. The condition often occurs after acute disease, and is manifested by headache, vertigo, mild delirium, pupillary alterations, and cramps in the extremities. It occurs in both the young and the old. Recovery is quite possible, but often at the expense of adhesions. Pachymeningitis hcemorrhagica is characterized by new formation of connective tissue upon the inner surface of the dura, this new tissue increasing in amount and becoming vascularized from the dura. With lapse of time it may form layers similar to those observed in aneurismal sacs. Hemorrhage from the more recently formed vessels often occurs, and clots an inch or more in thickness may result, which by their bulk cause serious com- pression symptoms. These lesions occur for the most part over the cortex, and when long existent may result in formation of cysts. The symptoms are vague, consisting mainly of headache, intensified with every new escape of blood, and, later, of paralysis, a study of which may reveal the site of the lesion. Gradual atrophy of one or both hemispheres may result. The pupils are usually contracted and immo- bile until compression is pronounced, when they dilate. In old cases we have optic neuritis; coma may’be the result of fresh bleeding. Dennis has paid special attention to these symptoms, and has urged trephining and exploration for the purpose of revealing the presence of a blood- THE CEREBRAL MEMBRANES. 67 clot and practically effecting its removal, if present. He has reported nine cases, some of which amply demonstrate the value of the procedure in cases previously doomed. Leptomeningitis.—This is often of the suppurative type, and results not merely from extension by continuity, but is often primary, or may be due to the breaking down of gummata, etc. Once existent, it spreads rapidly, the infectious agents having free access to the entire extent of the membrane along which they travel, even down to the end of the spinal cord. Its most frequent cause is disease of the middle ear, the infection spreading along the facial or auditory nerves. It is also often due to a sinus phlebitis and endocranitis—i. e. pachymeningitis externa— or it may spread from the nasal cavity. Prognosis is always bad. Many cases terminate in forty-eight hours; others may extend over two weeks. The general propriety of operations upon the cranium, for meningeal infections is now well established, but is too often made a forlorn hope when there is little or no possibility of any help. Could the operation be done earlier, in proper cases it would often be brilliantly successful. It is based upon the same principles which lead one to open other serous membranes when similarly infected. This requires of course the pre- liminary use of the trephine, perhaps at several points, with irrigation of the meningeal cavity, the establishment of drainage, etc. While always an operation of great gravity, it can never be more serious than the condition which may call for it. Surgical Treatment of Defects of Intracranial Develop- ment. There are numerous causes which produce imbecility- and kindred conditions in the young. Some are in effect congenital, some are post- natal. Within the past few years a number of these cases have been subjected to surgical operation, in many instances with more or less success; in a few with brilliant results. Mental defect may occur from injuries at the period of birth—mainly hemorrhages, for the most part cortical, though sometimes deep. In either case the clots thus formed frequently undergo cystic alterations. The term porencephalon is modern, and applied to changes comprising disappearance of real nerve- tissue with partial substitution by connective tissue, often with other degenerations, the result being atrophic alterations which apparently permit of no remedy. In a case of true porencephalon the outlook for operation is not at all encouraging, nor is it in any cases which are accompanied or caused by a genuine arrest of cerebral development. On the other hand, when the mental condition can be ascribed to the result of injuries, to hemorrhages, to meningeal irritation, to premature ossification, or too early closure of the fontanelles, or when it is accom- panied by evidence of meningeal irritation or any symptoms which point to a definite area of the brain as being the site of the principal disturbance, operation as a legitimate experiment may be conscientiously suggested and carried out. These operations have now been sufficiently tested during the past six or eight years to permit of certain generalizations, which are practically thus epitomized above. Even if epileptiform attacks are diminished in frequency, or mental irri- 68 INJURIES AND SURGICAL DISEASES OF THE HEAD. tability and continuous crying relieved, if local paresis disappear or optic neuritis seem to subside, if the athetoid condition may be diminished or spastic contrac- tions relieved (all of which things have been accomplished in various cases),— these of themselves will justify the attempt in any case which may seem at all promising. On the other hand, the outlook for imbecile or idiotic children is so unpromising, and the undesirability of prolonging their lives so self-apparent, that even a large percentage of mortality should not prevent the surgeon from offering such prospect as he may by operative measures. If one such child be made self- supporting or redeemed from hopeless imbecility by such operation, it would be no loss, but a relative gain to humanity, should nineteen similarly affected children perish in the attempt to produce this result. This, at least, is my own view of the subject. In accordance with the view, thus expressed, I have operated in nearly twenty cases with a mortality of about 25 per cent, and complete failure to obtain any improvement in about 88 per cent., while in the remainder of the cases more or less improvement, varying from slight to complete restoration to health, has been obtained. The operation is usually described as craniotomy or craniectomy, and is apt to be successful in many cases of microcephaly combined with idiocy. An acquired form will give a better prognosis than will the con- genital condition. The danger of the operation is often great, and espe- cially so since it is called for in puny, ill-nourished, and badly-cared-for children. To be successful it ought to be extensive. It should vary in character and degree—from simple division of the skull along the middle line, from near the root of the nose to the occiput on one or both sides, to the formation of large bone-flaps by cutting away a wide groove of bone so as to relieve pressure upon the hemispheres. The accompany- ing figures will present the various ways of performing the operation. It Fig. 17. Lines of removal of bone as practised by the author, by Lannelongue, and by others, can usually be made bloodless, or nearly so, by an elastic tourniquet around the skull. The incision in the skin should not correspond to the groove in the bone, but should overlap it some little distance. For my own part, I prefer to do most of these operations in two sittings. I would advise, as a rule, to prepare the scalp carefully for operation, to divide the skin along the proposed line, separate it from the pericranium and check all oozing, packing the longitudinal wound with gauze and putting on suitable dressings, and waiting a few days or until the child has sufficiently recovered from the shock of the first operation before SURGICAL TREATMENT OF EPILEPSY AND THE PSYCHOSES. 69 doing the second; then, at the second operation, after opening the skull with the trephine, to cut away with proper forceps (rongeur) along the desired line, or, if provided with it, to remove the bone by some surgical engine or revolving saw actuated by electricity. The strip of bone thus removed should be at least half an inch wide, and the overlying peri- osteum should be removed with it, since only in this way can the unde- sirably rapid regeneration of bone be prevented. By this means the dura is exposed, but not opened. In many cases this will be enough. In many others, however, it will be insufficient; and, could this be foreseen, it would be well to combine the above measures in one as a first operation, and then, a week or two later, to take out the gauze pack- ing and open the dura as the second procedure—this, however, only on the discovery by careful inspection that the wound is absolutely free from possibility of infection. Could infection be prevented, this is cer- tainly the safer procedure, since in young children to make a long scalp incision, to remove a long strip of bone, and then to widely open the dura is more than can be safely done in the majority of instances. It should have been carefully explained to those interested in the case that improvement will in all probability be extremely slow, and that little or nothing is to be expected at first, even if prompt recovery from the operation ensue. Neither would I advise any one to perform the operation unless parents are willing to assume all risks and abide by the results. SUKGICAL TkEATMEXT OF EPILEPSY AND THE PSYCHOSES. Operations for relief of epilepsy seem to date back even to the pre- historic era, and were for centuries done as a purely empirical measure; later, to have been practised with more or less plausible reason ; then to have fallen into discredit for long periods of time, with occasional re- vivals of the practice, until within the past ten or fifteen years the ope- ration has been again revived upon its merits and upon the recognition of more or less accurate indications. Operations of this character are based upon two fundamental facts : the first, the widespread experience that after various operations epilep- tic patients have been benefited; and, second, that a certain proportion of these cases, especially those of traumatic origin, are characterized by a localized and definite aura and by a systematic and practically invari- able order of muscle-involvement, according, it would seem, to some fixed law, and pointing definitely to a certain area of the brain from which apparently the irritation arises and spreads. This form of epileptic seiz- ure is that generally known as the Jacksonian, and is that in which ope- ration is most often of real service. In spasms of the Jacksonian type there is a certain order of progression which is scarcely ever violated. Thus, irritation beginning in the leg centre cannot reach the face centre without traversing that of the arm. It is possible also to have sensory equivalents for Jacksonian attacks, as when they commence with peculiar sounds indicating irritation in the centre of hearing, or with optical phenomena, or with disturbances of smell or taste, the former indicating occipital irritation, the latter irrita- tion in the temporo-sphenoidal region. 70 INJURIES AND SURGICAL DISEASES OF THE HEAD. The surgeon will often be consulted as to the wisdom of operation in the presence of this condition. In brief and in a general way, the fol- lowing statements may be made : It is necessary, first of all, to establish a traumatic origin, and epilepsy which has preceded a severe head injury can in no sense be ascribed to it. If it can be clearly established that it has followed injury, and if a distinct scar—especially a scar which is adherent—or depression can be discovered, or any area which is always irritable and which seems epileptogenic when irritated ; or if, again, by close study of the case it can be determined that the aura and the initial muscle-symptoms arise always in the same part—as, for in- stance, a finger, thumb, foot, etc.—and proceed according to a constant programme,—then one may say that operation is not merely justifiable, but advisable. On the other hand, when neither distinct scar nor dis- tinct history of localizing phenomena can be obtained operation should be attempted, if at all, absolutely as an experiment—an experiment which may be followed by good, yet one which gives little if any promise. Again, in epilepsy of the non-traumatic type, operation may be advised wrhen it assumes the distinctly Jacksonian form—i. e. when everything points to irritation proceeding from a localized portion of the brain. In the absence of Jacksonian symptoms operation is even more of an experiment than in the traumatic form. The operation itself is directed to excision of irritable scars, to exposure of the dura at the point of opening, to the detection and suit- able treatment of depressed fragments, dural adhesions, tumors, foreign bodies, etc. It is essential in every case that it be represented to those interested that the operation itself removes the cause, but cannot be, per se, expected to complete the cure, especially in cases of long standing, and that the final cure must depend in large measure upon the avoidance of subsequent irritation, upon the establishment of perfect habits of diet and excretion, which are often perverted, and perhaps upon the long- continued administration of drugs, of which the bromides are those most constantly given, perhaps with borax. The reader need not be reminded that old cases are the least favorable, and that recent cases are the most so for operation, and that the longer the diseased condition has existed the harder it will be to cure by any method. I believe thoroughly in operating in selected cases. I am equally con- fident that indiscriminate operation must lead only to disappointment and to occasional disaster. In the presence of long-standing lesions, like bone depressions, cystic degeneration of old clots, etc., the brain may have been so long pressed upon as to have become atrophied. The w'liole subject of the modern surgical treatment of epilepsy is inseparable from the topic of prompt and efficient treatment of all head injuries. Were the indications in these always met at the time of the accident, we should have a much smaller proportion of cases of traumatic epilepsy. Inasmuch as one object of many of these operations is to break up adhesions between the dura and the pia, one. is naturally anxious to know the result after such operations as to whether they do not speedily form anew. There is always this theoretical danger, and it is my custom in such cases to insert beneath the dura, at the point where such adhesions have been divided or torn, a piece of deli- INTRACRANIAL TUMORS. 71 cate gold-foil, duly sterilized, in order that it may separate these surfaces and pre- vent the recurrence of the old condition. Foil used for this purpose is perfectly harmless, and I have numerous patients in whom it has been used, apparently with- out producing the slightest disturbance. Mental and psychic disturbances after head injuries have been long known, and the suggestion to operate upon the skull in cases of so-called traumatic insanity is not new. In a general way, it may be said that whenever distinct mania follows a recognized lesion of the ver- tex of the skull, and fails to subside within a reasonable time and under proper treatment, there are the best of reasons for raising the scalp, tre- phining, and exploring as to the deeper condition. Patients might be redeemed from asylums who have long been inmates had this measure been practised at the beginning of their mental alienation. The same measure will give relief in certain cases of cephalalg-ia, or headache, where the pain is always ascribed to a particular region, and especially when there is tenderness over this region. These ope- rations are, of course, empirical, yet as the result of altered nutrition and allayed irritation, relief follows in a fair proportion of instances. Intracranial Tumors. Until within a few years these were regarded as having interest mainly for the pathologist and clinician, but as essentially hopeless so far as surgical help was concerned. Recent discoveries in the field of cerebral localization and recent experience with extensive openings into the cranium have shown, however, that a small proportion of intra- cranial tumors are of such a character and so located as to make them amenable to surgical relief. These tumors occur with about equal fre- quency in childhood and adult life. In the order of frequency they stand about as follows : Tubercular gumma, glioma, sarcoma, cysts, car- cinoma, and syphilitic gumma, with a small proportion of fibroma, etc. The gummata, either tubercular or syphilitic, are more common than all the other varieties put together. Cystic tumors may be the result of changes in previ- ous blood-clots or may be of independent origin. Parasitic cysts are in this coun- try exceedingly rare. Gumma pertains mostly to adults. Glioma is the most vascular of intracranial tumors, consequently has more of the erectile character, and may vary in size at different times. When there are marked variations of intracranial pressure there may be good reason for diagnosing glioma. The tumors most suitable for treatment are those which are firm, more or less encapsulated, non-vascular, and placed either on the dura, on or beneath the cortex, and in the cere- bral hemispheres. Tubercular tumors are seldom encapsulated, and about them there is usually a zone of infiltration which constitutes a dangerous area. Dermoid cysts may occur inside the cranial cavity, as well as outside. They are naturally of congenital origin, increase very slowly and insidiously, and are seldom pro- ductive of symptoms or signs. Tumors arising from the meninges may press upon, and later secondarily involve, the brain beneath, and are in most respects indis- tinguishable from tumors of the brain proper. These give rise to localizing symp- toms when pressing upon the motor and sensory centres. In other cases there will be vague complaint of pain. Of 100 cases of brain-tumor selected at random, not more than 5 to 7 per cent, are so placed as to justify surgical attack. In as many more at least the tumors are so located as to justify opening the cranium for mere relief of pressure without any notion or endeavor to attack the tumor itself. Before opening the cranium diagnosis should be made as 72 INJURIES AND SURGICAL DISEASES OF THE HEAD. carefully as possible—first, as to location ; second, as to whether cortical or subcortical; third, as to the number of tumors present; and, fourth, as to their general character. Location is determined in the main by study of pain complained of, by watching patients during convulsive seizures, by determining the extent of local or general paralysis, by careful his- tory which shall reveal the method and rate of extension of these symp- toms, and by the study of the optic disks, of vision, and by noting the presence or absence of stupor, nausea, coma, slow pulse, or other com- pression symptoms. Tumors in the sensory zone affect vision and speech, and reveal themselves largely by irritation symptoms. For instance, a patient with verbal deafness and marked hemiplegia probably has tumor in- volving the left superior or dorso-temporal gyrus, which, as it grows, would involve loss of muscle-sense and anaesthesia on the opposite side of the body. A patient with headache, vomiting, choked disk, stupor, increasing hemianaesthesia, lateral hemianopsia, without spasm or hemi- plegia, probably has a tumor in the white substance of the occipital lobe. If hemianopsia alone be present, there is almost always a tumor upon the inner aspect of the occipital lobe on the side opposite to the dark half- fields, which by downward growth may cause cerebellar symptoms. As to depth and number, the former may only be made out by study- ing the nature and location of the signal symptoms, the presence and order of appearance of the same, presence or absence of headache, and local changes in temperature. Tumors occurring in tubercular indi- viduals are probably multiple. When different centres or systems are involved we have also probably multiple lesions present. It has been generally held that the three cardinal symptoms of brain- tumor are optic neuritis, headache, and vomiting; and, while each of these is significant, and all of them are corroborative, they are not necessarily present nor does their absence exclude possibility of tumor. Other signs indicating the presence of tumor, it is a mistake to trait for the development of these three. The most distinctive feature of all intra- cranial neoplasms is the progressive character of such symptoms as are present. There is but one form of brain-tumor which is amenable to internal treatment—namely, syphilitic gumma; and in case of doubt it may be justifiable to keep the patient actively under the influence of iodides for a reasonable length of time. This, however, need never be prolonged far beyond two months. Should no improvement occur, to wait longer than this will diminish the benefit of surgical operation. Operation.—Brain-tumors are operated for two purposes: first, for relief of pain and other distressing symptoms in incurable cases; and, second, for radical cure if it may be achieved. Operation is justifiable in any case where pressure-symptoms become severe, particularly so when pain is localized to a reasonable extent. Choking of the optic disks is not infrequently relieved and threatened disability postponed. The operation when practised consists in, first, the exposure of the tumor; and, second, in its removal if possible. The tumor may be exposed by any of the methods to be dealt with below, the most serviceable probably being the osteoplastic method, by which a bone-flap is raised, along with the overlying scalp, from which it is not detached. The centre OPERA TIONS UPON THE CRANIUM. 73 of this flap is supposed to be calculated to overlie the centre of the deep lesion which it is proposed to attack. In many instances it is well to divide the opera- tion into two distinct procedures, the first consisting in removal of the bone and exposure of the dura; the second, a week or two later, comprising the balance of that which is to be done. But comparatively little shock attends removal of the tumor in the second stage of such a divided operation. After exposure of the tumor its cavity is best packed with a gauze tampon after prompt ligation of all bleeding vessels within the field of operation, although it is usually required merely on account of venous oozing, since it is often possible to cut to the depth of an inch in the brain without a single artery spurting except those in the pia. The tampon is of value if allowed to remain for forty-eight hours, as preventing filling of the cavity with clot or excessive bleeding during the vomiting which may follow the administration of the anaesthetic. In various brain operations I have been led to value highly the styptic properties of antipyrine, which I use ordinarily in 5 per cent, solution in sterilized water. I have no hesitation in spraying this upon the brain or in saturating tampons with it, which may be left in situ so long as necessary. A number of the old-fashioned small serrefines, properly sterilized, can also be resorted to, if needed, for securing vessels which may not be easily tied. They can be left in place along with the tampon until the third or fourth day, when all may be removed together. Next to the danger from hemorrhage is that of rapid oedema of the brain, which may result from increased tension in the arteries or through venous stasis, which later produces lymph-stasis, by which fluid collection in the tissues is still further facilitated. Another reason for using tampons is to prevent such relaxa- tion of veins as may predispose to this oedema. In most respects the operations for removal of brain-tumors differ little, if at all, from those whose general principles are elsewhere enunciated in this work. I am greatly in favor of using secondary sutures (i. e. those tied with bow-knots), which may be loosened on the second or third day, permitting the raising of the flap, removal of tampon, etc., and I employ them largely after all sorts of operations upon the cranium. It is my custom often to saturate the tampons which lie between wound-edges with an ointment com- posed of sterilized vaseline to which is added 5 per cent, of naphthalin. If this be placed between the raw surfaces, it prevents such union between them as will produce oozing when they are separated again for removal of the gauze. Or, instead of the gauze used for this purpose, we may employ the green-silk protec- tive introduced by Lister, which should have been previously carefully sterilized by soaking in strong antiseptic solution. Operations upon the Cranium, Memoranda in Cranial Topography.—The thickness of the skull varies greatly in different individuals or even in the same person. The very young and the aged are not provided with diplo'e; hence extreme care must be exercised in perforating their skulls. The skull is also thinner over the sinuses and the meningeal grooves. The middle meningeal artery enters through the foramen spinosum and divides into two branches; the anterior, that most often injured, passing across the anterior inferior angle of the parietal bone; the other passing nearly horizontally across the squamous bone. It is most often lacerated at the parietal angle. The frontal sinuses in many individuals are capacious, and by them in the naso-frontal region the tables of the skull are somewhat widely separated. The fissure of Rolando is the anatomical landmark whose position it is most important to determine with reference to a number of modern surgical procedures, since around it cluster most of the motor areas or centres. It commences at the middle line, about 56 per cent, of the distance backward from the glabella (root of the nose) to the inion (occipital protuberance), and, passing downward and for- ward, makes with the middle line an angle of 67° to 69°. For most purposes it is sufficient to say that it begins half an inch back of a point midway between the glabella and inion. It may be very easily located by Chiene’s method, which con- sists in folding a square piece of paper diagonally and folding this again; after which it is three-quarters unfolded, the acute angle then representing 672°. If this be properly applied to the skull, one edge of its surface can be made to fall directly over the Rolandic fissure. The fissure may also be located by a simple instrument known as the cyrtometer—a gauged metal strip having a sliding arm 74 INJURIES AND SURGICAL DISEASES OF THE HEAD. upon it, which, when the long strip is placed over the longitudinal sinus (i. e. the middle line of the skull), can be made to fall directly over the fissure. While neither of these methods is invariably and minutely exact, either of them is suffi- ciently accurate for all practical purposes. The fissure of Sylvius may be indicated by a line drawn from a point 3 cm. behind the external angular process to a point 2 cm. below the most prominent part of the parietal eminence. The short and ascending limb of this fissure is of relatively small importance in this connection. Reid’s base-line, so called, is a line drawn from the inferior margin of the orbit backward through the centre of the external auditory meatus. It is a line often alluded to in cranial topography. The colored plate (see Plate III.) will indicate with reliable accuracy the relation of the motor centres to each other and to the principal fissures and convolutions. It pertains merely to the left hemisphere of the brain, in whose third frontal convolution is placed Broca’s centre for speech, the corresponding area upon the right side having no exactly corresponding func- tion. The centre for vision, it will be seen, is located in the cuneus, the most basal portions of the hemispheres being the seat of the special senses of taste, smell, and hearing. Operation.—The word trephine is at present used both as a noun and as a verb, the older term trepan being now wellnigh discarded. The instrument itself, as at present made, consists of a section of a tube, one of whose extremities is arranged with sharply-cut saw teeth, the whole provided with a grip or handle, which revolves in a plane parallel to that in which the saw teeth cut. The best instrument is that arranged in a slightly conical manner, so that it may less easily burst through the Fig. 18. The Powell electric saw cutting a “trap-door” in the skull. skull and do harm to parts within. The trephine proper is manipulated by the hand. A variety of substitutes have resulted from applications of human ingenuity to the problem of opening the cranial bones. Some of these are actuated by foot or hand power, with reduplicated mechan- isms ; others by electricity. The more complicated the mechanism the more likely it is to get out of order, and there are but few of these substitutes which give anything like lasting satisfaction (Fig. 18). PLATE 111. FIG. i.

Localization of Functions. (Ziehen OPERA TIONS UPON THE CRANIUM. 75 In the common parlance of the day the operation of trephining is made to include any method by which an opening is made in the uninjured cranium or by which an opening already existing is enlarged and made to subserve the surgeon’s purpose. Aside from the saws already alluded to, there are in common use a variety of cutting bone-forceps, rongeurs of various device, and a variety of chisels, which are meant to be used in connection with the mallet or hammer. In order to use any of the latter instruments to advantage it is often well, and usually essential, to make the first attack with the trephine of reasonable size, say 2 to 3 cm. in diameter, after which forceps, chisel, or saw may be used as one sees fit. Straight saws are also of occasional usefulness, though not often now employed. For my own part, I prefer to use the chisel and mallet relatively seldom, feeling that the series of concussions resulting from blows of the hammer must add in at least an appreciable degree to the shock of the operation. The common trephine is provided with a centre-pin, which can be withdrawn after a shallow groove has been cut. To prevent slipping of the centre-pin I prefer to mark the point to which it is to be applied by cutting a little nick with the point of a chisel. In the absence of a wound, relieving one of the necessity of making incision, a flap of scalp is deliberately raised before applying the instru- ment. When the surgeon has his choice this flap is ordinarily of horse- shoe shape, and should be made with its convexity pointing toward the Fig. 19. Illustrating the use of the common trephine in depressed compound fracture. A horseshoe flap of scalp has been turned down, and the trephine is applied to firm, unbroken bone in order to make an opening through which the depressed pieces can be attacked and removed. occiput, since drainage is best afforded later by this arrangement. The old crucial incisions are now wellnigh abandoned. The pericranium is detached, after incision, with the periosteum elevator, and it is always well to turn it up with its overlying scalp without completely separating it. The scalp flap may be best held out of the way by temporarily sew- ing it to some other part of the scalp, every portion of which should be previously shaved closely and thoroughly scrubbed. The operator has his choice—to seize vessels as they bleed or to make the operation in large degree bloodless by applying an elastic tourniquet tightly around 76 INJURIES AND SURGICAL DISEASES OE THE HEAD. the scal]> above the eyebrows and beneath the occiput, the ears prevent- ing it from sliding. If the tourniquet be used, the vessels will often bleed in an annoying way after the wound is closed. If the operation be performed for fracture of the skull, should there be an opening already made by the depression of fragments it may not be necessary to use the trephine at all, but with suitable bone-forceps fragments may be removed or detached to the necessary amount. In this case, how- ever, there are often sharp points of bone which will require removal by cutting bone-forceps, for the surgeon should leave the margin of the bone-opening comfortably round and smooth. Should there be no open- ing into which the point of an elevator or of a bone-forceps can be in- serted, then one must be made; and it is for this purpose that the tre- phine is mainly used in cases of fracture of the skull (Fig. 19). It must now be applied upon a firm and undetached surface of bone, one which will bear the pressure necessary in the process of perforation. As used for this purpose, it should be so applied that at least two-thirds of the circle cut by its teeth will be upon unbroken skull; the remaining seg- ment of the circle may be over the fractured area. After it has begun to cut a distinct groove the centre-pin should be withdrawn and the instru- ment maintained in its position during its work by a firm and steady hand, which shall force it evenly through the bone and not exercise undue pressure upon one side or another. As the diploe is perforated the bone- dust becomes soft and bloody and the resistance is diminished. As the instrument sinks deeper, the operator must frequently intermit its use, and determine his position by means of the irrigator and of the probe or other instrument. The nearer one comes to the inner surface the more caution he must exercise, remembering that the bone is likely to be of unequal thickness. When the skull has been completely per- forated at one or two points around the little circle the operator should introduce the point of an elevator and pry up the disk of bone, or by rocking the handle of the trephine he may be able to remove the button with that instrument. When the operation is performed in the ideal manner the dura is scarcely injured, certainly not sawn through by the teeth of the instrument. In certain of the exploratory operations upon the skull large tre- phines, having a diameter of 7 to 10 cm., are occasionally employed, but the force required to actuate these instruments is so great as to speedily tire out the hand and arm of any but the most muscular indi- vidual. The time consumed is also fully equal to that which would be expended in cutting away the same amount of bone with suitable for- ceps. Before opening the dura every loose particle of bone and every splinter should be removed, depressed fragments should be picked out, and those which are semi-detached should be raised at least to their proper level. Through the opening thus made the dura is carefully examined; extradural collections of blood are recognized instantly, while some idea as to the amount of intracranial tension may be secured, even through a small opening. Nothing abnormal being discovered outside of the dura, should brain-tension be great or should the dura be discolored, as by blood beneath, the membrane should be opened, often again by a triangular or horse-shoe flap, and the subdural condition OPERATIONS UPON THE CRANIUM. 77 be accurately estimated. In some cases of meningeal hemorrhage clots will be ejected with no little force the instant the dura be opened. In other cases of intracranial pressure, either from tumor or from intra- ventricular hemorrhage, the brain will instantly protrude to such an extent as to make its reposition difficult or even impossible. When there is good reason for its use, one need never hesitate to employ a small aspirating needle in connection with some good suction apparatus. This may be passed to a considerable depth in the brain, when exposed from the vertex of the skull, without producing the slightest recognizable disturbance. By its use it is often possible to obtain most important information. Cystic accumulations, deep hemorrhages, etc. may be determined by this method. While the scalp incision may be made practically bloodless by employment of the tourniquet, as above mentioned, the blood may continue to ooze from the diploe or from the bone, and hemorrhage from this source be a constant annoyance. It may be checked by crushing the margin of the opening between the points of blunt bone-forceps, by which means the little vessels are compressed; or it may often be controlled, as suggested by Horsley, by forcing into the rough margin of bone some sterilized wax. Incisions in the dura should be made, so far as possible, parallel with its vessels rather than across them. When accessible, dural vessels can always he secured and tied. Vessels of the pia can also usually be picked up and secured with very fine catgut ligatures. The cortex itself is not so vascular as to afford much trouble. Upon any portion of the membranes or cerebral surface a sterilized solution of anti- pyrine can be sprayed or applied without hesitation (5 per cent, solution). In all deliberate operations sinuses are avoided so far as possible. When exposed or when necessary to attack them they may be ligated and divided, or may be packed with tampons of sterilized iodoform gauze, or may be seized with serrefines or light haemo- static forceps, which may be left for a day or two included within the dressings. Opening the skull, or, in general terms, trephining, is at present resorted to for the following purposes : 1. For relief of compression: a. By depressed bone, as in comminuted or gunshot fracture ; b. For removal of clot or ligation of vessels; c. For evacution of pus, either from the meningeal cavity or from a deeper abscess; d. For the removal of serous effusions, either extra- or intra- ventricular. 2. For removal of foreign bodies. 3. For relief of intracranial irritation—e. g. epilepsy, the psychoses, etc. 4. For removal of tumors. 5. To compensate for defective development. 6. For exploratory or purely empirical reasons, including the making of “relief openings” for relief of pain, etc. Aside from the ordinary methods of trephining as applied for ordi- nary conditions, modern surgery comprises the resort to essentially new methods for raising areas of skull of considerable size and then restor- ing them to their previous position. These are ordinarily spoken of as osteoplastic resections, and have added very materially to the art and resources of the surgeon. These consist, in a general way, of the forma- tion of a window, as it were, in the vertex of the skull by outlining a quadrangular or horse-shoe flap of scalp, which is detached only for a slight distance around the incision, after which, by use of the revolving saw or by chisel and mallet, a groove is cut through the bone running 78 INJURIES AND SURGICAL DISEASES OF THE HEAD. parallel with the margin of the scalp-flap, but perhaps a centimetre within it. After this bone area is completely cut through on three sides, it is then sprung up or elevated in such a way as to be broken across the base of the bone-flap. It is not at all detached nor separated from the scalp, and so when subsequently lowered into position retains its vitality by virtue of its vascular connections (Fig. 20). There is scarcely any reasonable limit to the extent to which this method may be resorted to, providing only that the bone be furnished with a sufficient blood-supply from undivided scalp. Consequently, the bone peninsula is made on a lower aspect whenever a large window is thus to be made. Whether this flap shall be immedi- ately secured in position with intimate and primary union, or whether it shall be made to cover a gauze packing for a few days, after which it may be restored to place, must depend on the purposes of the operation and the completeness of its performance in one sitting. The practice of replacing buttons of bone removed during trephining has not found general favor, and is employed by but few, since in ordinary cases the bone defect is replaced in time by fibrous and cicatricial tissue, practically as strong and resistant as the original bone. A much easier and equally effective method is to Fig. 20. “Trap-door” operation: bone-flap turned aside, dura exposed. “Osteoplastic resection.” sprinkle over tlie dura when closed some of the fresh bone saw-dust or some little fragments of bone, which shall be entangled in the clot and which may Subse- quently serve as centres of ossification. Where some particular measure seems indicated in order to atone for a large defect in bone, it has become quite customary to insert some artificial substitute, mainly either celluloid or a thin aluminum plate, pre- viously absolutely sterilized and cut at the time into such shape as may be called for, but a trifle larger than the real defect, being let in or sprung in, as it were, either completely beneath the bone or into the bony open- ing, so as not to be easily detached or slip out of the way. By this heteroplastic method most admirable results have been achieved. I have 79 used celluloid for this purpose in the spinal column also, closing with it the defect which remained after the extirpation of the sac of a spina bifida. OPERA TIONS UPON THE CRANIUM. The question of drainage will always arise. In a non-traumatic case, where every precaution has been observed, drainage will probably only be indicated when we are anxious to provide for the escape of blood or of cedeinatous elfusion. In these instances it can be made with gauze, strands of catgut, or some other capillary drain. In cases of injury to the head much will depend upon the nature of the case and the time which has elapsed between injury and operation. Should time for infection have been given, with probability of its occurrence, it is much better to insert an antiseptic packing, and to close the scalp, if at all, by secondary sutures. In other instances it may be enough to insert a capillary drain or to leave out two or three sutures from the lowest portion of the incision, providing in this way for the escape of material. Halfway measures, however, are most ill advised; and if one be in doubt, it is much better to leave the wound widely open than to close it in such a way as to in the slightest degree contribute toward retention of that which should escape. In brain-abscesses, etc. a rubber drainage-tube or cap- illary drain wrapped up in green-silk protective will certainly be required. External dressings should be both profuse and absorbent, and are best held in place by starched bandages. Absolute physiological rest should be insisted upon in the after-treatment, and the excretions should be kept lively, in accordance with the principles enunciated in the earlier portion of Volume I., in order that auto- intoxication in any form may be carefully guarded against. CHAPTER II. INJURIES AND SURGICAL DISEASES OF THE SPINE. E. H. Bradford, M. D. Spina Bifida. Spina bifida is a congenital deformity of the spinal column due to a lack of development of certain of its bony factors. As a result, the laminae of one or more vertebrae do not unite at the spinous processes and a space is left uncovered by bone. The gap may rarely involve the bodies of the vertebrae, but much more commonly is limited to the pos- terior portion only. As a result, the lesion is either in or very close to the median line. Through this opening the contents of the spinal canal may, and usually do, project, causing a tumor of variable size, Fig. 22. Fig. 21. Dissected sac in spina bifida (Warren Museum). which may be sessile or may be narrow at the neck, with a true pedicle. Of all the cases, 50 per cent, occur in the lumbar region, 12 percent, in the lumbo-sacral, and 7 per cent, in the sacral. Spina bifida is, then, the most common in the lumbar and lumbo-sacral regions, more rare in the cervical, almost unknown in the dorsal. The contents of the tumor Vertebra in spina bifida (Warren Museum). 80 SPINA BIFIDA. 81 may be the cerebro-spinal fluid, the cord itself, or, in the region of the cauda equina, the spinal nerves and nerve-filaments. If the sac con- tains the lining membranes of the cord and cerebro-spinal fluid, the tumor is called a meningocele; if besides the fluid the tumor contains the cord, it is termed a meningo-myelocele ; if the cord within the tumor is dilated with fluid, it is described as a syringo-myelocele. The second of these forms is the most common. The skin covering the tumor may be normal, but is more usually either thickened or thin or translucent. In some instances the skin is absent. There is usually a direct communication with the fourth ventricle through the pia mater at the lower border of the fourth ventricle. This communication, how- ever, may be obstructed, and in some instances there may be no communication between the sac and the spinal canal. The cord may be situated behind the sac, or it may be spread out on its internal surface, or it may lie in front of the sac. Pressure upon the tumor usually evacuates its fluid contents slowly, but only by increasing the amount of the cerebro-spinal fluid in the spinal and cranial cavity, often with symptoms of intracranial pressure. The amount or character of the contents can- not be positively inferred from the size of the tumor, nor does a large tumor necessarily presuppose a large loss of bony substance in the column. Sometimes the tumor may be so small as to be unnoticed. These cases seldom cause noticeable symptoms; exceptionally the reverse is true, and serious pressure-symptoms appear where the exciting cause is found to be bands of connective tissue at the level of the spinal opening, exerting compression upon the cord. This vari- ety is called spina bifida oeculta, and is often characterized by a patch of hair externally. The size of the tumor varies from that of a cherry to that of a cocoa- nut. If the tumor be of considerable size and the cuticle be at all thin, it may increase in size upon physical exertion, such as coughing, vomiting, sneezing, crying. The rapidity with which the tumor may be emptied under pressure indicates roughly the size of the open- ing in the spinal canal. The diagnosis usually offers no difficulty. If a child present a rounded congenital tumor in the lumbar, lumbo- sacral, sacral, or cervical region, in the median line, often varying in size, either with or without a pedicle, and with fluctuating contents, it certainly may be regarded as a spina bifida. The course of spina bifida varies. In the majority of instances the tumor ruptures during infancy, the fluid is evacuated, and the patient dies with convulsions or from a septic spinal meningitis. In some instances, however, a spontaneous recovery takes place, and in rare cases Fio. 23. Spina bifida in infant. 82 INJURIES AND SURGICAL DISEASES OF T1IE SEINE. the gap in the bone is closed by a subsequent bony growth. Such spon- taneous closure may be observed in a certain number of instances even where it is evident, from paralysis of the lower extremities, that portions of the cord are involved. In another class of cases the life of the child is not directly threatened, but serious symptoms are developed, due to the involvement of cord or nerves. In still another class of cases the condition continues indefinitely without serious symptoms. Treatment.—Treatment may be either conservative or operative. Conservative treatment consists of protection of the sac from violence and an effort to prevent the increase of the tumor in size. The tumor should be covered with absorbent cotton and a shield placed over it. The shield may be made of brass, silver, or aluminum, hammered over a plaster cast of the tumor. It may be held in position by a band Fig. 24. case of spina bifida. which encircles the child’s body or by adhesive plaster. Attempts to diminish the size of the tumor by pressure are manifestly irrational, and have been known to result fatally by developing a hydrocephalus, rup- turing at the anterior fontanelle. If the skin over the tumor become thin, a layer of cotton is to be placed upon the thinnest portion of the skin and held in place by collodion. Of operative measures, two only are worthy of attention: The first, the injection of an irritant within the sac ; the second, excision of the sac. Various methods of injection have been employed, but the following is most to be recommended : The sac is punctured on the side, the trocar being passed obliquely through the healthy skin, and a certain amount of the fluid is drawn off. If the sac is not large, it is better at the first tapping only to draw off a small amount of fluid. From one to two drachms of a solution of iodo-glycerin should then be injected sub- SPINA BIFIDA. 83 cutaneously (1 part iodine, 6 parts potassium iodide, and 50 parts glv- cerin). A moderately fine trocar should be used. After the injection the opening should be closed with dry gauze secured by collodion and iodoform. The surface of the tumor should be rendered scrupulously clean before the puncture is made. The operation may be repeated from four to six times at intervals of a week or ten days. This method has been especially advocated by Morton of Glasgow: its value was investigated by the London Clinical Society, which collected 82 cases (treated by Morton’s method); of these, 35 recovered and 37 died. In 5 there was no improvement, and in 4 there was slight improvement. Morton himself reports 67 cases, with 55 recoveries and 10 deaths. Powers has collected 15 cases, with 4 deaths. Excision of the Sac.—The treatment of spina bifida by excision of the sac has been successfully done in a number of instances. Various methods of operation have been advocated. An obstacle to a successful operation is met in the difficulty in preventing the copious escape of cerebro- spinal fluid, which by moistening the aseptic dressings becomes a source of infection. The simplest method of operation consists in dissecting lateral skin-flaps, opening the sac, returning into the spinal canal any nerve-structures that can be found, closing the divided and dissected emptied sac by means of careful suturing, and uniting the skin-flaps over the whole. Where the opening is large it is not desirable to sac- rifice much of the sac, but to fold it into the canal, stitching the opposing external surfaces. If the opening be small, the redundant sac-flaps should be cut off and the cut edges carefully sutured. The treatment of the skin-flaps must necessarily vary according to the size of the opening and the amount of skin. Osteoplastic methods have been used in the attempt to close the opening by dividing the arches of the vertebra and forcing them together near the median line, securing them by suture. Where the opening is small and the tumor is pedunculated, the sac which contains the dura can be ligated and covered by skin- flap. Attempts have been made to promote the growth of bone by means of trans- planted periosteum and by aseptic bone spiculse. Park of Buffalo has successfully closed the opening by the insertion of a celluloid plate. Hanson has collected 150 cases of spina bifida treated by excision since the introduction of antiseptic surgery: 25 of these were under the care of Swedish surgeons. The mortality from the operation in the whole number was 29 per cent. Robson thinks excision under aseptic surgery exposes the nerves in the sac to less irritation than the injection of an irritating' fluid. He has collected 20 cases of excision of the sac—4 cervical, 16 lumbo-sacral and lumbar. There were 5 deaths—1 on the table, 1 in thirty-six hours, 3 in from three to fourteen days. Of these cases he considers that in 1 the operation was not necessary, and in 2 was not advisable. There are manifestly three classes of spina bifida : 1. The slight cases, not threatening to burst or enlarge or seriously incommode the patient. 2. The cases beyond surgical reach, where operation is not indicated owing to the condition of the child and the size of the tumor. 3. In those cases where the deformity threatens either life, long disability, or death in time, operative measures are to be seriously con- sidered. It would seem that in the cases needing operative interference excis- ion is more thorough and surgical than puncture and injection of iodine, providing asepsis can be secured. 84 INJURIES AND SURGICAL DISEASES OE THE SEINE. It should be borne in mind that the percentage of spontaneous cure has not been accurately determined, and that cases have been observed where spontaneous recovery has taken place after spontaneous rupture of the sac with subsequent gradual narrowing and, in some instances, closing of the bony opening. Sacral Cysts. Tumors occasionally present themselves in the sacrum, with the cha- racteristics of fatty tumors, lying under the fatty tissue in the region of the buttock. These tumors are usually in the median line, but in some Fig. 25. Sacral cyst, showing defect in sacrum (Warren Museum) instances may lie somewhat to one side. The size of the tumor varies, and in some instances there may be fluctuation, though this is not always the case. If an incision be made, these tumors will be found to be filled with cerebro- spinal fluid, and if explored an opening will usually be discovered communicating, through another in the sacrum, with the spinal canal. These tumors are, in fact’ similar in nature to spina bifida occulta. Operative interference in these cases is a more'dangerous procedure than would be imagined, for the reason that it is diffi- cult to secure complete asepsis, owing to the leaking of the cerebro-spinal fluid after operation and the difficulty of securing a proper dressing in that portion of the body in a young child. Syringomyelia. This term is applied to an irregular enlargement of the central canal of the spinal cord, which, beginning as a congenital defect, is increased in later life, with corresponding disturbance in nerve-function, the most noticeable being a blunting of the sensibility to heat and cold, combined with impairment of the motor and tactile sense. The cavity, which may contain fluid, is sometimes so extensive as to encroach on the normal cord-structure, and give rise to loss of integrity of the parts affected by this pressure, with great disturbance in the" patient’s condition and activity. The affection is one which rarely comes to the attention of the surgeon. Keen mentions 2 cases of his own and 1 of Abbe operated COCCYGEAL DIMPLE AND SINUS.—FRACTURES. 85 upon by laminectomy : there was, however, no benefit, and the operation is of doubtful value. Coccygeal Dimple and Sinus. A small, shallow depression or dimple of the skin is not infrequently seen in the region of the coccyx. This is a vestige of the foetal opening of the spinal canal. The closure has been completed in these instances to such an extent that for all practical purposes the opening is entirely covered in, there remaining only a depression in the skin from the incomplete deposit of fat, similar to what is observed over a healed sinus or over the umbili- cus. There is in a coccygeal dimple, however, no evidence of scar or break in the skin. The depression when present varies in different individuals from a scarcely perceptible trace to a cul-de-sac of considerable depth, which may become the seat of inflammation. When the depression is suffi- ciently deep to form a sac, it may collect sebaceous matter, desquamated epithelium, or foreign substances, dust, cotton or woollen fibre, which, acting as irritants, excite inflammation. If the resulting suppuration do not find free vent, it undermines the skin and an abscess of con- siderable size may be developed. In certain instances the cavity con- tains a fold of hair growing from the normal skin which forms the wall of the sac. There is usually an opening from such a cavity, the coccygeal depres- sion forming a sinus which has been termed a pilo-nidal sinus, as it appears like a nest for the growth of a tuft of hair. Hair, however, is not invariably present. The affection often presents itself as a sinus of considerable size, with ragged granulating edges, in the centre of a mass of brawny skin and situated in the median line or the base of the coccyx. The sinus can be traced through the subcutaneous tissue to the peri- osteum covering the sacrum and coccyx and into a cavity of undermined tissue. The treatment is simple. The cavity is to be laid open freely, the inflammatory tissue forming the lining wall is to be thoroughly curetted, and a packing of iodoform gauze inserted to promote healing from the bottom of the cavity. INJURIES OF THE SPINE The injuries to the spine consist of— 1. Fractures; 2. Dislocations; 3. Fracture and dislocation combined; 4. A strain of the spine, with rupture of or injury to the mus- cles and ligaments; 5. Injuries to the cord and spinal column. Fractures. Fractures result either from direct violence, a blow from a height upon the spi ne, a fall, striking upon an irregular hard surface or projection, 86 INJURIES AND SURGICAL DISEASES OF TIIE SPINE. or from the violent bending or twisting of the spine. As considerable vio- lence is required to produce a fracture of the spine, the lesion is often accompanied by some displacement. If this be considerable, it amounts to a combination of fracture and dislocation. There is frequently also hemorrhage within the canal, and in many instances bruising or crushing of the cord by the displaced fragments. Fractures of the spine are not common, forming but 3-4 percent, of all fractures. They are more common in the dorsal and cervical region than in the lumbar, where the vertebrae are stronger. Fractures are more frequent in adult males than in women and children, as the former are more exposed to violence than the latter. The recognition of fracture of the spine is ordi- narily not difficult. The resulting disability is neces- sarily great, and the evidence of a local injury is manifest as a rule. There is frequently also proof of injury to the cord from paralysis of the bladder and rectum or of the limbs. In some instances, however, where there is but little displacement and the injury is in the anterior portion of the column, the lesion is only recognized by the injury to the nerves or cord, and is mani- fested by paralysis of motion or of sensation and the condition of the reflexes. As Keen has well expressed it, “ The spinal cord may be considered as made up of a series of hori- zontal segments, placed one on top of another like a pile of checkers, and one pair of nerves, right and left, arises from each segment. For example, the fifth cervical segment would be that segment of the spinal cord from which the fifth cervical nerve-roots take their origin.” These segments do not agree in position with the numerically corresponding verte- brae. Thorburn has called attention to the fifth-root group of muscles and the position assumed by the patient who has had the fifth cervical nerve crushed. Where this is injured the patient will lie with his arm in a peculiar attitude; or, in other words, if the fracture be below the fifth cervical nerve there will be abduction and flexion at the elbow, the hand will be supinated, and the humerus externally rotated. If the fifth cervical nerve be involved, the deltoid muscle is paralyzed and the elbow will lie next the body. At other levels the position will not be so character- istic. The area of anaesthesia, also varies according to the level of the injury. In general, it may be said that the outer parts of the upper extremities correspond to the upper nerve-roots, the inner portions to the lower. Starr concludes that in the spinal cord the centres of control of the bladder and rectum are always affected together. Control over these sphincters is lost when the lower three sacral segments are involved. The condition of the reflexes will indicate an injury to the cord at certain Fig. 26. Fracture of body of vertebra (Warren Museum). FRACTURES. 87 points, and it is possible with careful examination to determine whether there is a total or partial transverse lesion of the cord. Complete tram- verse destructive lesions of the cord will give complete muscular paralysis of the parts below the level of the injury, complete ancesthesia below the level of the injured nerve, and there- fore complete abolition of the knee- jerk and deep reflexes; but if the Fig. 28.

Fracture of spine with displacement: section of vertebrae (Warren Museum). fransvet'se lesions of the cord are partial, the muscular paralysis and anaesthesia will be incomplete. The visceral reflexes, especially those of the bladder and rectum, are affected in the same way. Differential Diagnosis of Diseases and Injuries of the Spine and Spinal Cord. Fracture. Dislocation.

Gurlt reports 217 deaths in 270 fractures, but statistics are not of absolute value unless they are still further classified according to the nature of the accident and site of the fracture. Treatment.—The treatment is either non-operative or operative. Operative treatment consists of laminectomy for the purpose of re- moving from the cord the pressure of extravasated blood or loose spic- ulae of bone. Chipault advocates early interference if an operation is to be done, owing to the fact that degenerative alterations of the cord take place within twenty-four hours, as has been shown by experiments on ani- mals and autopsies. Lauenstein believes that even if there is incontinence of urine and faeces, with cystitis and bed-sores, an operation is justifiable, as recovery cannot be expected without operation. Horsley is definitely in favor of an operation in all cases where there are symptoms which would show pressure upon the cord. Bur- rell analyzed 168 cases, and advocates ope- ration in the first twenty-four hours in all cases of fracture, even including those in the cervical region. Thorburn has reported 61 cases of operation, with 35 deaths; Chipault has collected 95 cases, with 38 deaths; Lloyd has found mortality of 57 per cent, after operation. The danger from an operation in- creases with the height of the lesion. Where the fracture is limited to the arches, with displacement, an operation is manifestly indicated. Chipault concluded that in cases of lumbar or sacral fractures surgical interference Fig. 29. Specimen of consolidated fracture of the spine (Warren Museum). 1 From Dennis, by permission. 90 INJURIES AND SURGICAL DISEASES OE THE SPINE. should be undertaken at once if there be prominence—i. e. deformity. If there be a permanent and irreducible displacement of the bony frag- ments, and the fracture can be reduced by manipulation or is reduced spontaneously, operation should be delayed, but if the case remains stationary, interference is justified toward the end of the first month, but not later. An operation is not indicated if it is certain that the cord is de- stroyed. Where it is uncertain, as is usually the case, and where there are symptoms of constant pressure upon the cord from hemorrhage, laminectomy is to be advocated. The procedure, however, is one which in itself involves considerable danger, and should not be undertaken if it be clear that the patient is unable to endure the shock of the operation : this, however, is a question which can only be determined on examina- tion of each case. A description of the operation of laminectomy is given later. Non-operative treatment of fracture of the spine consists in placing the trunk and spinal column in such a position as will promote healing. This can be done in an ordinary fracture bed, steadying the patient by sand-bags if necessary. The fixation of the patient’s trunk in plaster- of-Paris bandage is of assistance "where it is possible. Some surgeons have recommended the suspension of the patient, with or without an anaesthetic ; the procedure is, however, not without danger. The method of application of the plaster corset upon the patient lying in a sheeting hammock, such as is used in caries of the spine, as described elsewrhere, has much to recommend it. No anaesthetic is required, and a convenient method for an attempt at rectification of the malposition following injury is afforded. It should be borne in mind that it is essential that the spine be placed in such a position that the fragments are as nearly as possible in normal relation. Sagging of the bed is to be prevented, and it is sometimes necessary to arch the spine forward (as in Pott’s disease) by the use of pads. Traction is sometimes advisable, especially in the cervical region. It may be said that the fixation and placing of the patient are not unlike that necessary in Pott’s disease. Especial care is neces- sary to guard the patient from bed-sores. Dislocation op the Spine. Ashhurst has collected 394 cases of severe injuries to the spine, of which 124 were pure dislocations, the remainder being dislocations with fractures. It is difficult, however, if not impossible in many instances, to make a certain diagnosis between the two injuries. As a rule, the dislocation is bilateral; in some instances it is unilateral. Unilateral dislocation of the spine in the cervical region produces a twist of the neck resembling torticollis. The face is turned to the opposite side, and abnormality in the line and position of the spinous and transverse pro- cesses with muscular rigidity is present. If the dislocation be higher, there will be dyspnoea. In some of these instances the torticollis from high cervical caries following an injury is regarded as an old dislocation. The appearance and symptoms are somewhat the same, and there is a noticeable twist, with an alteration in the position of the transverse and spinous processes. A diagnosis can, however, be made by a careful investigation of the history of the case, as the torticollis from disloca- DISLOCATION OF THE SPINE. 91 tion appears immediately after the injury, while that from caries is developed more gradually. In bilateral dislocation the head is thrown back, the chin raised. Dislocation of the Occipital Bone from the Atlas.—Stimson claims that there are three undoubted cases of this extremely rare acci- dent, which is almost invariably fatal. Extraordinary violence is required to produce this lesion, as this articulation is very strongly pro- tected by ligaments and muscles. Dislocation of the atlas from the axis is not so uncommon. It is, however, always fatal. The chin is found flexed upon the chest. Death is almost immediate, and comes from the injury to the respira- tory centres. In dislocation of the lower five cervical vertebrae the patient’s face is usually drawn away from the side of dislocation. There is a prominence on the dislocated side, the muscles being put upon the stretch Fig. 30. Fracture dislocation with great displacement—patient almost completely recovered (Park) upon that side; those upon the opposite side are relaxed. There is deviation of the spinous processes. There is frequently deformity inside the pharynx. Dislocation without fracture in the dorsal and lumbar region is extremely rare. Forcible reduction of dislocation of the spine is necessarily a pro- cedure of gravity. In the cervical region it has been done with success. Great care is needed in the administration of the anaesthetic. An assist- ant steadies the trunk, while the surgeon, standing at the head of the operating table, holds the patient’s head (in cervical dislocation) firmly between his hands, the fingers grasping the back of the neck, the palm pressing upon the lower jaw, and with the thumb reaching under the chin : the necessary amount of traction and manipulation is thus possible. After the correction of the deformity the patient should be placed upon a bed-frame and the head steadied by means of sand- bags. 92 INJURIES AND SURGICAL DISEASES OE THE SPINE. Wounds of the Spine. The penetrating- wounds of the spine result either from violence, the use of knives or missiles in war, or from accidents, splinters with penetration of wood, cutting instruments, or falling. They either injure the bone alone or, entering the canal, divide the cord partially or com- pletely. The larger vessels near the column may be injured, causing death by hemorrhage. If the bone alone be injured, the case involves no great danger. The wound should be thoroughly cleansed and recovery can be expected. Where a large artery is divided an exploratory incis- ion is necessary, with control of the hemorrhage by haemostatic forceps. In some instances it is impossible to reach the bleeding bone, when pressure by means of packing with antiseptic gauze is all that can be done. In the neck, where the vertebral artery lies close to the column, hemorrhage is to be especially dreaded. When the wound of the back involves injury to the spinal cord, the symptoms are much more alarming. In some instances, though they are exceptional, the membrane alone is injured. Ordinarily, the cord is either crushed, divided completely across, or partially incised. Cases of injury of the entire cord above the fifth cervical segment are neces- sarily promptly fatal. Other cases are recorded of partial incision of the cord which have been followed by almost complete recovery. Where there is injury to the cord there is necessarily paralysis, either complete or partial accord- ing to the extent of the injury. It should be remembered that if the division of the cord be unilateral, the paralysis is a cross-paralysis, as has been pointed out by Brown-Sequard and confirmed bv 78 carefully recorded cases. The paralysis of motion is on the side of the injury, while on the opposite side there is impairment or loss of sensation. The treatment of this injury should be governed by ordinary sur- gical indications, such as cleanliness and drainage. Where vessels are injured the hemorrhage should be checked. In some instances it may be necessary to explore the wounds to see if any foreign body remain in the canal. Thorburn has collected 34 cases, with 21 recoveries—3 com- plete, 16 with a persistence of some motor or sensory impairment. Gunshot Wounds of the Spine.—These injuries may vary from the perforation of small portions of the spinal column to the most extensive destruction. The nature of the wound depends somewhat upon the size and range of the missile. There is always considerable shock following the injury, and the lesion is necessarily grave. The lower in the column the wound, the less the mortality; in the cervical region the mortality, according to the Medical and Surgical History of the Civil liar, is 70 per cent.—63 per cent, in the dorsal and 45 per cent, in the lumbar region. The symptoms vary with the extent of the injury and the part injured. Where the missile gives rise to contusion of the spine, there is a temporary disturbance of the function of the cord. Wounds of the muscles or injuries to the ligaments give rise to stiffness of the back. In some instances suppuration and necrosis follow. Where the spinal canal is opened there may be escape of cerebro-spinal fluid, though this symp- tom is not constant. Where the cord is injured there is partial or 93 SPASM OF THE SPINAL COLUMN. complete paralysis, with resulting anaesthesia and hyperaesthesia. The transverse and spinous processes are more frequently injured than the bodies, but when the latter are wounded the lesion is necessarily more grave. The treatment consists in cleansing the wound, establishing drain- age, and removal of foreign substances and of such spiculae as can be easily reached. A thorough exploration, with removal of the spinous process, or a laminectomy for the relief of pressure by hemorrhage, would be indicated under certain circumstances where there is a his- tory of paralysis following the injury after an interval of freedom from paralysis. Park has operated on one case of gunshot wound of the spine and cord, the ball entering the chest, passing through the lung, and lodging in the vertebral column, where, after opening the spinal canal, air entered the chest through the bullet-track, the patient thus breathing partially through his back. Spasm op the Spinal Column. The spinal column is firmly held by strong ligaments and protected by muscles: it is not, therefore, as liable to receive the slighter injuries as the less protected articulations. In severer injuries, however, it may sustain the same lesions as other articulations, and a sprain of the spine will give rise to distressing symptoms analogous to the sprain of the large joints. Even when there is no injury to the bony structure or to the cord patients will suiter pain, distress on motion, and disability from the rupture of the ligamentous fibres connected with the spinal support. Many of these cases, combined with the nervous disorganization accom- panying invalidism and following an injury, present functional symp- toms not dissimilar to those seen in the traumatic neuroses. Patients of this class need careful treatment. Sufficient amount of rest should be enforced to permit healing of torn ligamentous fibres, followed by such measures as will improve the circu- lation and diminish the congestion and local swelling following sprains. Massage, electricity, and gymnastic exercises (carefully graded) will gradually effect a cure. Contusions and sprains of the trunk following railway accidents pre- sent certain features. From the medico-legal complications to which railroad injuries often give rise, the symptoms vary greatly according to the condition of the patient, and are often complicated with studied exaggeration and malingering. The symptoms are at first those of a contusion or sprain, followed by those which result from the confinement after an injury, and resembling those seen in neurasthenia and general invalidism. These are recognized by their varied and ill-defined character, unlike those of a true organic lesion. It is often necessary that the injury should be treated at first as if a severe contusion were present: after the lapse of sufficient time for recovery from any traumatism, if symptoms still are present, they should be treated as neurasthenic cases are treated, by muscular development and stimulants to the circulation, muscle-building, and nerve-training. These cases are not to be confounded with those of true malingerers, where recovery takes place immediately after the verdict. 94 INJURIES AND SURGICAL DISEASES OF THE SPINE. Concussion and Contusion of the Spinal Cord. The existence of contusion of the spinal cord has been questioned, but there is apparently no doubt that a severe lesion may take place in the cord without any external evidence of injury. Gull has reported a case where death followed within fifty-five hours after an accident, with no external evidence of injury. At the •post-mortem examination some small extravasations of blood into the anterior and posterior cornua and in the posterior columns were found. There had been complete paralysis in the upper and lower extremities. Hulke has reported a case where there was an imperfect recovery from paralysis, and Bastian has reported a case where death occurred six months after the accident, a fall of twenty-five feet. There was no evidence of fracture or compression upon the cord nor injury to the structure of the cord, but there were microscopic lesions in the substance of the cord, with secondary degeneration and atrophy of the sympathetic ganglia. These lesions had developed without external mark of violence. After the accident there was complete paralysis of motion in the leg and paralysis of the right arm. The patient had recovered somewhat after the injury, but contractions had persisted. The importance of these few cases lies in the fact that they appear to support the theory that although the spinal cord is carefully protected in the canal, both by the solidity of-the.structures which surround it and by the strength of the attach- ments which support it, yet in some instances of comparatively slight violence without external injury, lesions in its structure may take place. It is difficult to explain, the physical laV by which such injuries are inflicted, but the facts cited seem, beyond question. •; Spinal Hemorrhage. Hemorrhage may take place in the cord or within its membranes— i. e. they may be extradural or subdural. It may also occur in the structure of the cord itself, a lesion termed heematomyelia. Gowers claims that this is a rare lesion, whereas Thorburn considers it not infre- quent, and in examining 21 cases of injury to the spine found it in 6. It is more common in the cervical region. Where the hemorrhage is sufficient in extent to destroy the tissues paralysis and atrophic changes result. If, however, the lesion simply give rise to compression, the symptoms subside as the blood absorbs, leaving spastic symptoms in the lower limbs if degenerative changes have taken place. The attack is sudden, a distinct interval of time usually elapsing after injury, with paralysis and anaesthesia below the point of lesion and retention of urine and faeces. Where the hemorrhage is in connection with the membranes the lesions is termed hcematorrhachis. It may be under the arachnoid, within the dura, or outside of the dura. ( Vide Plate I V.) Laminectomy has been performed for spinal hemorrhage, and, although the results up to the present time are not encouraging, yet the procedure is indicated in every instance where the patient’s condition warrants any surgical intervention. Pott’s Disease ; Spondylitis ; Vertebral Caries. Pott’s disease, or caries of vertebral bodies, was first described by Percival Pott in 1779. It consists of a destructive ostitis affecting the spongy tissue of one or more of the bodies of the vertebrae. The ostitis is tuberculous, and is similar in character to tubercular ostitis seen in the epiphyses of the long bones. The changes in tubercular PLATE IV. Intraspinal Hemorrhage, mostly Subdural, with Minute Subpial Ecchymoses. (Park.) POTTS DISEASE; SPONDYLITIS; VERTEBRAL CARIES. 95 ostitis are described elsewhere in this work (Volume I. Chapter XXXV.). Owing to the superincumbent weight of the head and shoulders pressing upon the carious vertebral bodies, the spine and trunk become peculiarly and characteristically distorted. The morbid process is limited, as a rule, to the bodies; the transverse, articular, and spinous processes are rarely primarily affected. Tubercular ostitis of a vertebral arch has been reported by Roberts of Phila- delphia. Primary disease of the intervertebral cartilage must also be extremely rare, if it exist at all. Various portions of the vertebral bodies may be affected. There may be two or more foci in one vertebra or the whole body may be affected. Disease of two vertebral bodies in different non-adjacent parts of the spine has been observed. The number of vertebrae involved in the extension of the morbid process necessarily varies: in some instances the bodies of twelve or even more have been diseased, with a distortion of the whole column. The caries is aggravated by the pressure thrown upon the affected vertebral body; portions of the diseased bone become absorbed; the vertebral body becomes excavated or yields; the spine bends forward above the seat of the disease, and backward angular deformity at the point of disease results. This extends as more vertebrae are involved : the knuckle or projection is seen in the back; this enlarges and the so- called “ humpback ” results. This projection is to a certain extent modified by compensating curves in the healthy portions of the spine and alteration in growth in the shapes of the healthy bodies, and peculiar characteristic distortions result. The process may be arrested, the development of healthy bone take place, and a natural cure with deformity results; or the process may extend beyond the curative efforts of the cicatrizing ostitis, and necrosis with caseous foci and abscesses may result; which latter, extending to the adjacent tissues, discharge, forming sinuses, followed by prolonged suppuration with accompanying sepsis. Deformity inevitably results, with death in the severest cases, though ultimate recovery may take place even in cases regarded as hopeless. The ostitis extends to the adjacent tissue, involving the spinal canal and attacking the spinal cord and its membranes, giving rise to a pressure paralysis. This is not due to the narrowing or dis- torted shape of the spinal canal, except in rare instances, but comes as the result of an external pachymeningitis. Inflammatory thickening of the dura results; myelitis follows in certain instances, with ascending and descending secondary degeneration. The process may arrest itself, leaving no permanent change or a slight sclerosis, or the whole cord may be reduced to a fraction of its normal size. Paralysis may also be caused by the pressure of an abscess, and in rare instances by loose frag- ments of bone. In severe cases of angular deformity the chest becomes disturbed, with secondary pathological changes in the shape of various viscera. The shape and capacity of the chest are very much altered, and the ribs sometimes sink into the pelvis or rest upon the crests of the ilium. Hypertrophy of the heart may follow. Narrowing of the cavity of the aorta has also been noticed by Lannelongue. A cure, however, is possible even if the deformity be very pronounced, but the correction of a pronounced deformity cannot be effected. Etiology.—Authorities differ as to whether the affection is more 96 INJURIES AND SURGICAL DISEASES OF THE SPINE. common in males or females. The disease is probably equally frequent in the two sexes. It is much more common in childhood, beginning at the fifth year in nearly one-third of the cases. Gibney found that 87 per cent, were under fourteen years of age. It would appear, although statistics vary, that the theory advanced by Taylor is a plausi- ble one—namely, that the regions most liable to disease are those most exposed to jars or increased pressure, and that the disease will be more frequent at the hinges of motion in the spinal column or where there is the greatest exposure to violent jars. The determining cause of caries of the spine is in all probability a jar or superincumbent pressure upon a tissue which is incapable of resisting slight injury, and which becomes thus exposed to the invasion Fig. 32. Fig. 31. Caries in cervical region. Caries in high dorsal region. of the tubercle bacillus. Statistics as to an inherited predisposition or diathesis would indicate that an inherited lack of resistance is in many instances a factor in causation. Symptoms.—The symptoms of caries of the spine vary to a certain extent according to the portion of the spine affected. They may be classified as follows: First, those symptoms which are due to irritation of the nerves proceeding from the spine; second, those due to a stiffness of the muscles of the back and of the spinal column; third, to peculiar- POTT’S DISEASE; SPONDYLITIS; VERTEBRAL CARIES. 97 ity in attitudes from the inability of the spine to bear superimposed weight. Typical cases of Pott’s disease are so characteristic that the diag- nosis is evident at a glance from the singular deformity of the back; but in the early stages some experience is necessary in recognizing the affection. Peculiarity of attitude due to muscular stiffness, referred pain, or nervous disturbances are then prominent early symptoms, and may be present before a projection has been noticed. The peculiarity of attitude is due either to reflex muscular spasm similar to that seen in joint dis- Fig. 34. Fig. 33. Caries in mid-dorsal region. Caries of spine, with psoas contraction and old sinuses. ease, or to an unconscious effort on the part of the patient to prevent jar or any increased pressure upon the affected vertebral bodies. This attitude necessarily varies according to the point of the spine attacked. In the upper cervical region it resembles that of wry neck; in the lower cervical or upper dorsal region the chin is held somewhat raised and the spinal column below the point of disease is straighter than normal; in the middle dorsal region the attitude noticed most frequently is an ele- vation of the shoulders, sometimes with one held higher than the other, and some lateral deviation of the spine; in the lower dorsal or lumbar Vol. II.—7 98 INJURIES AND SURGICAL DISEASES OF THE SPINE. region the patient, in the early stage, will be frequently noticed to lean backward. The patient walks upon the toes, with the knees bent so as diminish the jar of the spine. These peculiarities of attitude vary according to the severity of the disease. They may be at one time more noticeable than at another. A certain amount of muscular rigidity of the muscles of the back will be found on palpation, and it will be noticed that children become more easily tired, and after playing for a while will desire to lie down, rest their arms upon a chair, or support the head with their hands. The amount of muscular stiffness and rigidity is, in a measure, an index of the degree of activity of the dis- ease. In addition to the spasm of the muscles of the back, the attitude is affected by contraction of the psoas muscles and in such cases as pre- sent psoas contraction: abscess, beginning or developed, is to be sus- pected. In the early stages this contraction is slight, but as the disease progresses it may be present to such an extent that locomotion on the leg is difficult. Double psoas contraction sometimes occurs, crippling the patient. Pain may be present in Pott’s disease to a very severe degree, but, as a rule, this stage is only temporary, and in some cases pain is entirely absent. The pain complained of is not in the back, but is referred to the peripheral ends of the nerves in the cardiac, abdominal, or epigastric region, or frequently in the thighs and legs. In caries of the cervical region it may be referred to the back or to the top of the head. The pain is ordinarily slight, aggravated by jar, and may be only occasional, but severe attacks accompanied by hypersesthesia are sometimes noted. Analogous to these attacks of pain are disturbances of other nerves, manifesting themselves in dyspnoea with cyanosis, digestive disturbances, nausea, vomiting, and troubles of the bladder. These attacks may sub- side, and recur at intervals without apparent cause. Tenderness on pres- sure over the spinous processes is rarely present. When tenderness of the back is observed, it is more an evidence of functional neurosis than of caries. Tenderness of the spine may occasionally be observed in Pott’s disease from a general hyperesthesia. This, however, is diffuse and not sharply localized. Paralysis in caries of the spine may be present at any stage of the disease. It is sometimes partial, but may become complete paraplegia. Out of 295 patients with caries of the spine, Gibney noted paralysis in 62. In 189 cases of caries of the upper dorsal or cervical region, paral- ysis occurred in 59. In 106 cases of lower dorsal and lumbar caries, paralysis occurred in only 3. Deformity in Pott’s disease is characterized by the backward projec- tion of one or more spinous processes. This is due to the carious dis- ease of the vertebral bodies forming the anterior support of the spine. The spinal column above the disease falls forward, throwing certain of the spinous processes into prominence, and thus causing a projection of one or more of them. The adjacent vertebrae become more or less involved in the disease or altered in shape from the altered pressure, it being found, as a rule, that as the projection is sharper the disease is more acute. The deformity tends to increase until either a spontaneous cure results or until the carious bone has solidified by cicatrization. The deformity may involve the whole of the dorsal region, and cause also an unsightly dis- POTT’S DISEASE; SPONDYLITIS; VERTEBRAL CARIES. 99 tortion of the chest. This consists of a thrusting forward of the sternum, with a projection of the lower portion of the sternum and abdomen, giving a contour caricatured in the well-known traditional figure of Punchinello. Abscess is a frequent complication of Pott’s disease. Caseous foci extending from the diseased bone may cause sufficient irritation to form an abscess, which, projecting from the vertebral bodies into the thorax or abdomen, extends down under the fasciae and comes to the surface in various regions. In the cervical region, abscess may point in the throat (retropharyngeal) or in the neck. Dorsal caries may develop thoracic abscess, evacuating itself in the lung or passing through the muscles and pointing in the back or sides. The most common place, however, for abscess in Pott’s disease is in the inguinal region or in the groin, passing under Poupart’s ligament and developing in Scarpa’s triangle—the classi- cal psoas abscess. Before passing through Poupart’s ligament, abscesses may accumulate in the inguinal region, dissecting up the peritoneum and presenting a large subperitoneal abscess. The contents of such abscesses are pyoid or sero-purulent fluid containing caseous masses. Frequently calcified or bony spiculse are present, and in some instances the contents are cheesy, with but little fluid. Abscesses may be absorbed and disappear. In a majority of instances, however, abscesses press to the surface and ulcerate through the skin, and thus evacuate their contents. If they open spontaneously in such a way as to be completely evacuated, they may eventually heal, but in many instances the contents are only par- tially discharged. Some caseous matter remains, and, although the external opening of the sinus is closed, a later reappearance of the abscess may take place. In other instances the discharging sinuses per- sist with pent-up pus, and eventually exhaust the patient by the accom- panying septic processes. Diagnosis.—The early recognition of Pott’s disease is of the utmost importance. The diagnosis where marked deformity is present is easy. A backward projection of the spinal column from the median line of the spine is pathognomonic. The curve in chronic rheumatic arthritis, rickets, aneurism, or malignant disease is round, entirely different in appearance from the sharper angular projection in Pott’s disease. In severe scoliosis the trunk may be as badly distorted as in Pott’s disease, but the humpback is a projection of the rotated and distorted ribs and not of the spinous processes. In examining the patient at an early stage the child should be entirely undressed, made to stand upon a table or to walk across the room; the position in which the child holds itself, the gait in walking, the attitude in stooping to pick something from the floor are to be carefully noted. The patient should then be laid upon its face on a table or hard bed, and the flexibility of the spinal column tested by lifting the child’s feet and legs with the face downward. The child should also be turned upon the back. The backward extension of each thigh should be examined to determine whether any projection of psoas muscle on either side is pres- ent. The abdomen should also be palpated in the inguinal region. Where cervical caries is suspected the attitude and movements of the head should be carefully noted. The patient should be seated upon a lounge or the floor and directed to bend forward so as to touch the toes 100 INJURIES AND SURGICAL DISEASES OF THE SPINE. with the hands if possible, and at the same time bowing the head for- ward so that the chin should touch the chest. The normal flexibility of the spine varies in individuals, and in children it is much greater than in adults. The forward and backward flexibility is greatly diminished where caries of the spine is present, even at an early stage of the disease. Stiffness in rotation of the spine should also be examined by causing the patient to turn while the pelvis is firmly held. Where caries of the spine in the dorsal region is present stooping forward to pick anything from the floor is difficult, and only done by holding the spine in a stiff* posi- tion quite characteristic of the disease. This is not true, however, in Fig. 35. Test for stiffness of the spine: normal flexibility. caries in the cervical region except in the more acute stages, at which time disease is unmistakable from the presence of other symptoms. The peculiarity of attitude in early stages of Pott’s disease may be noted as a torticollis, a lateral deviation of the spine, an unusual attitude with raised chin and elevated shoulders, bent knees, or an exaggerated back- ward bending at the lumbar region, varying with the portion of the back affected. The seat and localization of the pain and nervous symptoms are cha- racteristic, more in connection with other symptoms than from anything noticeable in the pain itself. They are ordinarily classed by the parents POTT’S DISEASE; SPONDYLITIS; VERTEBRAL CARIES. 101 and attending physicians as rheumatic or neuralgic attacks. A grunting respiration and frequent belly-ache, continuing at intervals for a long period, are both significant. The recognition of a projecting knuckle in the earliest stages of Pott’s disease is not always easy. In the cervical region the muscles may be thick and the projecting spine masked. The sixth and seventh cervical spines are normally prominent, and frequently the first dorsal also; the last dorsal and the first or second lumbar are often more prominent in health than the other spinous processes. These projections, however, are not sharp and do not interfere with forward or backward flexibility. Any projection of the spine in the middle dorsal region should be regarded as a symptom of great significance, as a physiological projec- tion of one of the spinous processes in the mid-dorsal region is not observed. Peculiarities in the line of spinous processes are to be seen in lateral curvature, and in some instances of cancer and sarcoma of the spine, in aneurism and rhachitic curves of the spine in small children. The first is easily distinguished from Pott’s disease by the twist or rota- tion of the spine, while rhachitic curves are rounded. This is also true of the spinal curves due to carcinoma, sarcoma, and aneurism of the spine. The recognition of paralysis is not difficult after it is developed; beginning paralysis is sometimes overlooked. It is characterized by exaggeration of reflexes, knee-jerks, and ankle-clonus. Abscesses are recognized in the early stage by palpation and the recognition of psoas contraction. Pott’s disease may be confounded with traumatic neuritis of the spine (railroad spine), hysterical spine, rheumatoid arthritis, and sacro-iliac dis- ease. Other mistakes in diagnosis have occurred, but are due more to an ignorance of the ordinary symptoms of Pott’s disease than to any inherent difficulty in the diagnosis itself. Mistakes in diagnosis between low caries and acetabular hip disease have been made, but can be avoided if it is borne in mind that in hip disease flexion in abduction of the lame thigh is interfered with, while in caries of the spine motion in abduction is as free on the lame as on the other side; and this is usually true of flexion. A distinguishing characteristic of traumatic neuritis of the spine or the neurasthenic or hysterical spine, as compared to Pott’s disease, is that in the so-called functional alfections local tenderness in the back is usually present, but is almost invariably absent in Pott’s disease. In rheumatic arthritis the stiffness of the spine is not sharply localized, but involves nearly the whole column; there is usually little muscular spasm, no unusual projection of the spinous processes; the ribs are ankylosed to the spine, and a full expansion of the chest is interfered with or the amount of expansion is noticeably limited. Prognosis.—Caries of the spine is necessarily a disease of long dura- tion. It involves a severe deformity unless checked, and is attended by severe complications, paralysis, and abscess, and at times alarming symptoms. Facts, however, show that the disease has a tendency to recovery in many cases, but with the development of deformity. Under thorough treatment deformity can be prevented, the symptoms relieved, and patients entirely cured. Pathological specimens, however, show 102 INJURIES AND SURGICAL DISEASES OF THE SPINE. complete bony union and an entire cessation of the carious process, and clinical evidence in abundance can be cited to prove complete recovery in a large number of instances (Fig. 36). In the autopsies at the Munich Pathological Institute on patients with Pott’s disease 24 out of 31 were found to have hypertrophy of the right side of the heart; 4 had muscular degeneration of the heart-walls; 2 had stenosis of the mitral valve; 1 showed acute miliary tuberculosis; 8 died of phthisis, 4 of pneu- monia, and 1 of carbuncle. In one of Lannelongue’s specimens of stenosis of the aorta following Pott’s disease the aorta only measured 16 mm. at the origin of the brachio-cephalic trunk, 12 mm. after the carotid had been given off, and only 8 mm. in the region of the second lumbar vertebra. In another specimen the lumen of the aorta was reduced to a mere slit. The prognosis of abscess depends largely upon the situation of the abscess and the possibility of complete evacuation. The prognosis in adults is not as favorable as in children. The tendency of the deformity is to in- crease during the period of activity of the disease, as well as in the period of growth of a twisted spinal column—a tendency especially marked in the upper dorsal region. Cases of arrest of the disease and spontaneous cure without marked deformity occasionally occur in upper cervical and in lower dorsal dis- ease, but in the upper and mid-dorsal regions the tendency to an increase of deformity is proportionate to the extent of the disease. In some cases arrest of growth of the whole child takes place, apart from the loss of vertebral sub- stance. This is especially true in upper dorsal disease. A peculiarity in the shape of the face is also seen in cases with severe deformity of the trunk. Paralysis in Pott’s disease shows an unusual tendency to recovery. Taylor and Lovett found that of 59 cases ana- lyzed, 39 recovered entirely, 3 recovered in part, 5 died of an intercurrent affec- tion, and in 12 the termination was not known. Where the bladder and rectum were paralyzed the percentage of recov- eries was much smaller. The average duration of paralysis was somewhat less than one year. The disappearance of paralysis was gradual, recovery of sen- sation appearing first, then that of motion. The recurrence of paralysis occurred in a few cases. Marked paralysis of sensation indicates an extensive myelitis, but some impairment of sensation is found in a majority of cases. Paralysis of sensation may be marked, and yet recovery result.

POTT’S DISEASE; SPONDYLITIS; VERTEBRAL CARIES. 103 Treatment.—As the course of Pott’s disease is a long one, treat- ment through many years is necessary. The measures used, however, vary with the pathological conditions and the activity of the process. The principles of treatment of caries of the spine are simple, though their practical application is attended with difficulty. The diseased vertebral body should be protected from jar and pressure until a cure is accomplished. As in ostitis elsewhere, there is an effort toward repair, and everything should be avoided which would hinder this reparative process. The jars which come upon the spinal column are chiefly those received in bending the column forward, and pressure upon vertebral bodies comes from the superincumbent weight of the head and trunk. In treating a diseased vertebra the superincumbent weight should be removed from the part affected as far as is practicable, and all bending forward avoided. To prevent deformity the spinal column should be made as straight as possible and secured in a straightened position. A relapse will occur unless it be supported while the bone is not sufficiently solidified to endure a jar without reawakening an ostitis but partially healed. If the proper conditions are granted, it is possible to effect a cure without a deformity. Although it is sometimes difficult to secure the requisite conditions for a sufficiently long time, yet prevention of the increase of the deformity in all cases, and even diminution of slight deformity in some instances, can be gained by thorough treatment. The methods of treatment may be grouped as—first, recumbency; second, the use of appliances or corsets. Recumbency.—If the patient lie upon the back or upon the face on a hard surface, there is no superincumbent weight pressing upon any portion of the spine. If the patient lies upon his back upon a sagging bed, the spine is bent and some pressure upon the vertebra results, though the superimposed weight is removed. For this reason it is not sufficient in treating caries of the spine by recumbency that the patient be placed in bed: the spine should be held in such a position that the forward concavity of the column should be as slight as possible or ob- literated entirely. The method of treatment by recumbency has certain manifest disad- vantages. It is irksome to the patient and the attendant. It removes, however, superincumbent weight entirely, and it is therefore of use in the acute stage for the purpose of preventing an increase of the inflam- matory process, and of diminishing it by lessening the irritation from jar and superimposed pressure. It will be found in practice that patients who have suffered from attacks of neuralgic pain during the painful stage of Pott’s disease, will after a short period of thorough fixation become less restless and irritable, will gain in general condition, and be free from pain. It is difficult to secure sufficient fixation in the recumbent treatment without the use of some form of fixation frame. The gouttilre of Bonnet, though admirable in its efficiency, is cumbersome and expen- sive. Its advantages can be secured by a light bed-frame, made as follows: Four strips of steel bar or four strips of ordinary gas-pipe half an inch in diameter are fastened together, making an oblong frame of the patient’s height and width. The steel bars can be riveted at the ends or the gas-pipes can be secured in the ordi- nary gas-fitter’s rectangular joint. This frame is covered tightly with stout cotton sheeting, wound about the frame, made tense, and secured at the sides. If this is placed upon a bed, the patient can lie upon it as comfortably as upon the ordinary mattress. The patient can be secured to this frame by straps about the shoulders 104 INJURIES AND SURGICAL DISEASES OF THE SPINE. and hips and, if necessary, about the knees. The child can be lifted on the frame and carried about easily. The sheeting can be changed when soiled; an opening should be cut in the region of the buttock, so that the bed-pan can be used. A Fig. 37. Bed-frame. traction adjustment can be added at the ends of the frame. The great advantage of this apparatus is that the patient, while thoroughly protected from jar, can be Child in bed-frame. moved in an appliance that is neither cumbersome nor expensive. In the severest cases, in addition to the frame, fixation of the trunk by the employment of a plas- Fig. 39. Child in bed-frame, with head traction. ter jacket or corset is sometimes advisable to secure the patient from any twisting in sleep. In ordinary cases, however, the frame alone is sufficient, but the use of pads placed under the back, pressing the spine forward, is of advantage. These POTT’S DISEASE; SPONDYLITIS; VERTEBRAL CARIES. 105 pads can be made of saddler’s felting, and should be of sufficient thickness to raise the projecting portion of the spine. They should be placed at each side of the spinous process, and can be secured to the sheeting to prevent slipping. In cervical or high dorsal caries a light traction upon the head is of advantage. This can be made by a head-string fastened to the patient’s head and secured to the top of the frame or to a weight-and-pulley attachment at the head of the bed ; counter-pull is furnished by a belt secured to the lower part of the frame, or, if a weight and pulley is used, by raising the head of the bed. Treatment by Plaster Jacket.—The most ready method of treatment of caries of the spine is by the plaster jacket introduced by Dr. Sayre. The advan- tages of this method are its ready applic- ability, its cheapness, and the fact that it places in the hand of every practitioner an efficient means of treatment. It can- not be said, however, that a plaster jacket is applicable to all cases of caries of the spine. It is a method which can be used with benefit in suitable cases. Some skill is required in application. A poor jacket does harm rather than good, and deceives the patient and the physician. In applying a plaster jacket the patient should be placed in the recumbent posi- tion or else in as straight a position as possible, with the curve corrected as much as practicable by suspension. Plaster bandages prepared in the usual way are wound around the patient’s trunk, with the patient kept in a cor- rected position until the plaster has become hard. When the disease is situ- ated in the mid-dorsal region the patient is firmly supported by this means. In the cervical or high dorsal region a plaster jacket is of use simply as a base for the support of some form of head-retention. The simplest Fig. 40. Jury-mast for high dorsal and cervical caries. Fig. 41. Frame for application of plaster jackets in recumbent position. of these is what has been termed a jury-mast, which consists of a bent steel rod serving as a support for a head-sling. Instead of the jury- 106 INJURIES AND SURGICAL DISEASES OE THE SPINE. mast, which is unsightly, an arrangement can be used supporting the head beneath the chin and occiput which is less of a disfigurement. In lower lumbar caries, where much lordosis is present, a plaster jacket Fig. 42. Application of a plaster jacket in the recumbent position. should be applied, with the patient’s back hollowed slightly in a position of lordosis and with but slight suspension to diminish to a minimum the intervertebral pressure. Fig. 43. Apron for antero-posterior support. During the application of the plaster bandage the patient should either be sus- pended by the head or arms, or both, or a plaster jacket can be applied with the patient recumbent, lying face downward upon a tight sheeting support, like a flat POTT'S DISEASE; SPONDYLITIS; VERTEBRAL CARIES. 107 hammock. The hammock, made of stout sheeting, can be made tense by means of pulleys, and if slit, as is recommended by Brackett, along the patient’s sides, the surgeon can apply plaster bandages snugly. When these are hard, the sheeting hammock is cut and can be pulled out from beneath the jacket. The details of the application of the plaster are of importance. Projecting spinous processes or bony portions of the pelvis are to be protected by saddler’s felt placed at both sides of the bony projection. The plaster should be well rubbed into crinoline free from glue or sizing, which will delay the setting of the plaster. The bandages should be well rubbed in as they are applied, and should be applied after having been thoroughly wet. If the details are properly attended to, the bandages become hard in a few minutes. Proper material should be used tor the bandages. Cloth with too close a mesh cannot retain a sufficient amount of plaster, and holds moisture too long to admit of rapid hardening. Too coarse- meshed cloth, while allowing rapid setting, makes a jacket which is liable to crumble. Plaster jackets are to an extent uncleanly, and for that reason uncomfortable; and occasionally an eczema will develop under the jacket, abscesses or chafes may be present, without attracting the immediate attention of the surgeon; but these Fig. 44. Fig. 45. Thomas collar for cervical caries. Head-ring, front view. difficulties are to an extent obviated by skilful application and frequent renewal of the jacket. A plaster jacket can be split and lacing-hooks fastened to the sides of the cut, and the corset removed and reapplied at pleasure. This, however, does not furnish as firm a support as the unsplit bandage, and should not be used except in convalescent cases. As a substitute for split plaster jackets, and their superior in durability, a cor- set of leather or paper can be made. This is shaped upon a cast taken from a plas- ter jacket used as a mould. Sole leather is wet, stretched, and hammered upon this cast, and thoroughly dried; if necessary, it can be strengthened by steel strips and fastened with the requisite lacings. Paper jackets are made by pasting upon the cast with white paste strips of thick matrix-paper thoroughly wet. Four to six layers of this paper are used; between each two layers strips of crinoline or linen are added, with a layer of crinoline inside and outside: the whole should be dried thoroughly, and the resulting corset split and removed from the cast. It can then be painted and varnished, and forms a stiff light jacket. Another form of jacket is made by the use of thin strips of wood fastened by glue. Corsets have been made of strips of steel woven wire and of aluminum. The latter are expensive, and hardly more serviceable than those of paper or leather. 108 INJURIES AND SURGICAL DISEASES OF THE SPINE. Treatment by Means of Braces.—The treatment by means of braces has fallen into discredit from the fact that the application of spinal supports has been left too often to mechanicians whose object is more to sell their appliances than to cure the patient. Furthermore, the proper application of braces requires some experience and skill and attention to detail. The brace consists of a strong steel support which is fitted to the back when the patient is recumbent, lying upon the face with a straightened spine. To this the patient is fastened by an apron carefully fitted in the front and secured to the brace behind by straps and buckles. The uprights of the brace lie on both sides of the spinous processes, and pads secured to a firm pad-plate are fastened to the uprights at such points as will bear the greatest pressure when the patient is erect. It will be seen after the patient is firmly secured, while in a recumbent position, to a firm steel brace, that in an erect position the amount of forward bending will be slight, the pro- jecting portion encountering the resist- ance of a firm and unyielding brace. The successful employment of braces depends upon the careful attention to detail in the way of proper straps, pads, and buckles. The brace should be altered from time to time as the patient alters in shape. It will be readily seen that the stiffness of the brace should be sufficient to sustain a possible forward bending of the spine. Braces are often made light, allowing some spring, thus impairing their usefulness. It should be remembered that all possible forward bending increases the jar upon the affected vertebral bodies, and therefore is to be avoided. The attempt should be made to transfer, as far as is possible, the weight upon the articulating pro- cesses rather than upon the bodies. In the upper dorsal and in the cervical regions proper attachments are neces- sary for the support of the head. These attachments either consist of a jury-mast or, better, a circular ring or collar, which supports the head. When properly fitted these appliances are not unsightly, but their proper adjustment needs care. Fig. 46. Wire head-support attached to antero-posterior splint for cervical and high dorsal caries. Selection of Method of Treatment.—It should be clearly borne in mind that no one form of treatment is applicable to all stages of a dis- ease nor to all cases. In the selection of the method of treatment the pathological condition should be carefully considered. In the acute stages absolute and complete recumbency should be enforced, and in such a position as will not only relieve the weight from the affected vertebral bodies, but diminish the pressure as far as possible. In the subacute and convalescent stage the erect position, which is essential for health, and therefore for the establishment of a reparative process, should be allowed, but only allowed when the back is firmly fixed in such a position as will as nearly as possible prevent any additional jar on the unsound verte- bral bodies. Whether that should be done by some form of corset or of brace depends upon the amount of nursing facilities at the disposal POTT’S DISEASE; SPONDYLITIS; VERTEBRAL CARIES. 109 of the patient. Braces require more attention and more care. They are more precise, and therefore better, than a corset. In the mid-dorsal region, however, a carefully applied plaster jacket gives a support which is both firm and convenient, and requires no especial nursing. In the cervical and upper dorsal region braces are more effective than the cor- set and jury-mast, but require some skill in proper adjustment. Treatment of Complications.—Lumbar and iliac abscesses constitute a formidable complication. Authorities differ as to the relative advan- tages of expectant treatment over that of early operation. The facts are, that a certain number of cold abscesses in the spine become absorbed if Fig. 47. Fig. 48, Antero-posterior support: back view. Anteroposterior support with head-ring for high dorsal caries : side view. the carious process is arrested. In a certain number the contents tend to evacuation, and, if they can be thoroughly reached with the knife and suitably drained, this should be done. If, however, they are in a region where drainage by spontaneous opening is more thorough than that given by early operation, the expectant treatment should for a time be employed. Where abscesses become large they need to be opened, and this should be done by a free incision under aseptic precautions. In lumbar abscesses the opening should be made in front and back by an incision in front, above Poupart’s ligament, near the anterior superior spine, and behind in the region between the ribs and iliac crest. 110 INJURIES AND SURGICAL DISEASES OF THE SPINE. The Treatment of Psoas Contraction.—This deformity should be treated by correction under an anaesthetic or by traction by means of weight and pulley. In resistant cases osteotomy may be necessary. Paralysis.—The natural course of paralysis is toward recovery, and the use of medication is therefore of uncertain value. The same is true of the actual cautery, recommended by the earlier writers. I n some instances laminectomy is of advantage, but exact value of this procedure in Pott’s disease is not as yet determined. In view of the fact that the percent- age of recovery of cases properly treated is nearly 100 per cent., the advantages of laminectomy can only be urged where thorough treatment has been tried and failed, where care cannot be furnished for a sufficiently long period to establish a cure, or where the patient is becoming worse after a long period of careful treatment. Acute Osteomyelitis of the Vertebra. This affection, which differs clinically from tuberculosis of the verte- brae or Pott’s disease, has been described by Tournadour, Lannelongue, Witzel, Stanley, Konig, Valleix, Huron, Deaver, Lloyd, Chipault, Morian, and Keen. The invasion is, as a rule, more violent than in caries; there is more fever and muscular spasm of the muscles of the back ; later there are swelling and suppuration. In a third of the cases the arches are attacked. In the cervical region the head may be drawn back as in cerebro-spinal meningitis; later there are swelling and pain in the region of the spine. In some cases there is paralysis of some of the limbs, varying with the portions of the nerves attacked. Diagnosis is not always easy in the early stages. Where it is pos- sible for a diagnosis to be made the treatment by direct incision, disin- fection of the parts affected, and drainage, recommends itself. In many instances, however, the expectant treatment is necessary from an inability to recognize the disease. The disease is a dangerous one, but spontane- ous recoveries have been reported. Cases have been reported by Gibney, and also by Osier, with symp- toms referable to disease of the spine following typhoid fever. The “ typhoid spine,” as it is termed by Gibney, is perhaps an osteomyelitis following typhoid fever, or an affection resembling osteomyelitis with less acute invasion than in the instances hitherto reported. (Hide Volume I. Chapters XIV. and XXXV.) Curvatures of the Spine not Due to Primary Bone Disease. In addition to what is termed angular curvature or Pott’s disease, already described, there is common a lateral curvature or scoliosis, in which the spinal column is distorted by curves due to faulty habits in attitude, paralysis, or weakness of muscles. These curves are termed kyphosis (the curvature with a convexity backward) and lordosis (curve with a convexity forward). Strictly speaking, the angular curvature in Pott’s disease is a form of kyphosis, but the term also includes other more common curves, especially the deformity known as round shoul- ders. This affection is usually the result of bad habits in standing and sitting, due either to muscular weakness, occupation, or in some instances CURVATURES NOT DUE TO PRIMARY BONE DISEASE. 111 to near-sightedness. In rapidly-growing children the muscles of the back have not the required strength to maintain for a long time a correct posi- tion : the arms and scapulae drop forward, and in order to balance this altered weight the patient leans backward at the waist, protrudes the belly, and throws the head somewhat forward, giving a stooping attitude. The same result is produced by those whose occupation obliges them to maintain a stooping position for many hours in the day. In children with rickets or paralysis, owing to the weakness of the muscles a kyphotic attitude is assumed in a sitting position. In rheu- matoid arthritis and osteomalacia, and sometimes in malignant diseases of the spine, the spine is arched back- ward. In the early stages of curvatures without alterations in the shape of the bone, the spinal column can be made straight with but little difficulty. After a time, however, the bodies of the spine become altered, the liga- ments adapt themselves to an abnor- mal position, and the curve becomes a fixed one. In the early stage of round shoul- ders the curvature can be corrected by drilling the patient to maintain a correct attitude. If there be muscu- lar weakness, special gymnastic exer- cises are of importance. Appliances are, as a rule, not advisable except in Pott’s disease. Lordosis.—The forward bending of the spine (convexity forward) oc- curs as a deformity often secondary to other conditions, such as congenital dislocation of the hip. It may result, however, from simple weakness of the erector spinse muscles. The patient assumes this position in order to balance the trunk in such a way that the weakened muscles are not called upon to act. This is also seen in pseudo-muscular hypertrophy. It is seen also in early symptoms in Pott’s disease and in children with large abdomens. Patients with ascites or abdominal tumors, as well as pregnant women, assume naturally this position. When the deformity exists in a mild form, due to a muscular weakness from overgrowth or from any non-organic cause, it is benefited by gymnastic exercises for the purpose of developing the lumbar muscles. In some instances a back-brace or a removable corset is of advantage to relieve the patient from the strain of the erect posi- tion, but it should only be used in exceptional cases and for a short time. Massage and electricity are useful as adjuvants. Fig. 49. Spondylitis deformans, or rheumatic arthritis of spine. 112 INJURIES AND SURGICAL DISEASES OF TIIE SPINE. Spondylolisthesis.—This term is applied to a rare affection which consists of the dislocation forward of the last lumbar spine where it articulates with the sacrum. A few cases of this has been reported. They were the result of the relaxation of ligaments after confinement. The use of a stiff corset and the employment of crutches constitute the treatment. Spondylitis Deformans. This name is given to chronic rheumatoid arthritis of the vertebral articulations. It is characterized by stiffness of the spine and a curva- ture with the convexity backward. In many instances it is accompanied by ankylosis of the articulations between the ribs and the spinal column, and in many, but not all, instances by rheumatoid arthritis in other joints. The affection is more common in old age, but is occasionally seen in children. It is to be distinguished from Pott’s disease by the fact that the stiffness is not narrowly localized, and from a characteristic rounding in the curve, which is entirely different from the angular or sharp curve in Pott’s disease. (Vide Fig. 49.) The prognosis is not favorable. The treatment is similar to that in use for chronic rheumatoid arthritis elsewhere. The operations which have been performed and recommended on the spinal column may be grouped as follows: A. Laminectomy: 1. To enter the canal, open the dura, and examine the injured cord and relieve the pressure of hemorrhage in case of hemorrhage ; 2. For the reduction of dislocation of the vertebrae or removal of spiculae; 3. For the removal of any tumor of the dura or any foreign body pressing upon the cord ; 4. As a means of examination and exploration of the vertebral bodies in Pott’s disease. B. Operation upon the sacrum and coccyx. C. Vertebral puncture for the relief of excess of cerebro-spinal fluid. Laminectomy.—The object of this operation is to relieve the spinal cord of any pressure which may be exerted upon it, with the least pos- sible mutilation of the tissues involved in its structure. The indications for this operation have already been spoken of under the headings of Fracture of the Spine, Pott’s Disease, and Spinal Tumors. The tech- nical details, however, need special attention. The dangers of laminectomy are chiefly those to be encountered from the depth and importance of the tissues and structures attacked. Horsley has called atten- tion to the dangers of hemorrhage, and Keen lays special stress upon the shock following the operation. Especial care should be taken in administering the anaes- thetic. The patient should be brought to the edge of the table, so that the face should project, and placed upon the belly or nearly so, with the face turned to the side, giving the anaesthetizer an opportunity to thoroughly inspect the face. Incisions of different shapes have been recommended. A long, straight, median Operations upon the Spinal Column. PLATE V. Osteoplastic Resection of Posterior Vertebral Arches. (Urban.) OPERATIONS UPON THE SPINAL COLUMN. 113 incision is, however,sufficient in all cases,unless an osteoplastic resection is attempted, when an inverted U-shaped incision is advisable. ( Vide Plate V.) The skin, mus- cles, and fasciae are to be divided, the spinous processes and arches laid bare: the muscles are to be separated from the arches by a knife rather than by raspatory. Time is not to be lost by the use of haemostatic forceps unless large vessels are divided, which is ordinarily not the case. Hemorrhage is to be controlled by packing the wound, by pads, or by hot water. Osteoplastic resection, although advocated by some, is not to be recommended; the subperiosteal division, being shorter, is preferable. After the spinous processes and the arches are cleared attempts should be made to remove the bony tissue. For this purpose the saw, forceps, mallet and chisel, and the trephine have been used, but the simpler the Fig. 50. Specimen of laminectomy of spine (Warren Museum). method the better. The periosteum is to be pushed back from the spinous pro- cesses and arches as far as possible, and by the use of a pair of strong bone-forceps, made for the purpose with a flat plate on the under side, the arches are to be di- vided on each side, care being taken to avoid wounding the dura or the nerves as they emerge from the spinal column. It is necessary to remove several laminae, the size of the opening into the canal depending upon the amount of the cord it is necessary to expose. Fatty tissue will be found lying in the canal. It can be separated by blunt dissection; the dura is freed from the canal by means of a director, and the cord felt through the dura. In case of extradural lesions, these can be inspected, and the condition of the dura and the contents of the spinal 114 INJURIES AND SURGICAL DISEASES OE THE SPINE. canal determined. It is advisable, if possible, to avoid opening the dural cavity. When it is necessary the incision of the dura should be a straight, median incision. After the operation, in case any is needed, the dura should be closed by sutures, the muscular flaps brought together, and the skin sutured. It is advisable to drain the wound for a few days by means of a gauze wick, as considerable oozing follows the operation. No drain, however, should be inserted within the canal. In some instances it is desirable to suture the muscles and ligaments. A bed-frame after the operation, or a fracture-bed, will be found of assistance. Patients lie most comfortably upon the back after the operation: lying upon the face facilitates attention to the wound and obviates the necessity of turning the patient for that purpose, but does not permit of as complete drainage of the wound as a position upon the back. Attempts have been made to reduce the deformity following fractures or dislo- cations by cutting down upon the spinal column and forcing the displaced frag- ments into position; but such a procedure is of doubtful efficacy. Spiculse of bone can be removed—the condition of the bone examined. Correction of the malposition is to be effected when possible with much circumspection to prevent further injury of the cord or nerves. Laminectomy in Pott’s Disease.—The spinal canal is opened in caries of the spine to relieve the cord from pressure, and laminectomy for that purpose does not differ from the ordinary procedure. It has also been recommended as a means of examining the condition of the vertebral bodies. This can be done by separating the dura from its bony attach- ment in the canal, using a curved director for the purpose, and explor- ing the posterior surfaces of the vertebral bodies by means of a probe or director, pushing the dura and cord gently to one side. It is not always necessary that a complete laminectomy should be done for this purpose : opening the canal by removal of the arches on one side will be sufficient unless more room is required. Measures have been recommended for the examination of the vertebral bodies without entering the vertebral canal. This is of value in wounds of the spinal column without injury to the cord for the examination of the bodies in tubercular ostitis, as well as in osteomyelitis. The tech- nique varies in different parts of the spinal column—viz. in the lumbar region, in the dorsal, and in the cervical region. Lumbar.—This procedure was described by Treves in 1884 as follows: A straight incision is made from the last rib to the ilium, 2J inches to the outside of the median line; the incision reaches to the border of the quadratus muscles, and the tips of the transverse processes should be felt; careful dissection should be continued down to the psoas muscle. The peritoneal cavity is not to be opened. By means of large retractors, such as are used in nephrectomy, the wound can be explored at its lowest depth, and by blunt dissection the side and anterior surface of the bodies examined by the huger. Dorsal Region.—Boeckel in 1882, Hartman, Vincent, and others, have all recommended similar operations in the dorsal region. Schaeffer advises an incision to the side of the line of the spinous processes, which uncovers the tip of the transverse processes of the affected vertebrae and the head, neck, and part of the body of the corresponding rib. To avoid wounding the pleura, sympathetic ganglia, the spinal nerves, and the intercostal arteries, the rib is to be divided at the level of the tuber- osity. The transverse processes are then to be removed, the bone being free from either attachment by blunt dissection. Vincent has suggested OPERATIONS UPON THE SPINAL COLUMN. 115 boring from the side through the carious vertebral body and passing drainage through this opening. Cervical Region.—It lias been recommended to attack the vertebral bodies in the cervical region through the mouth. There are manifestly objections to this plan. The lateral method is much preferable; this can be done in the following way : An incision is made on the posterior border of the sterno-mastoid, the length depending upon the depth of the region to be attacked. The superficial veins and nerves are to be avoided as far as possible. The sterno-mastoid and omo-hyoid are to be raised, and the space bounded by the splenius, omo-hyoid, and posterior scalenus is reached; the longus colli is to be dissected through. Great care must be taken to avoid the vertebral arteries and nerves. Another method has been suggested, which consists of the incision at the level of the larynx, passing down to the lateral edge of the thyroid body close to the larynx, dividing the tissues internally to the common carotid. A small retropharyngeal opening is made, and this is gradually dilated. The first of these methods is manifestly the better. Wiring' of the Spine.—Wiring of the spinous processes has been recommended and performed by Hadra. Ligature of the transverse processes, tying together of the laminae, suture of the spinous processes, have also all been recommended after laminectomy and in cases of frac- ture, but have none of them found general acceptance. Operations upon the Sacrum.—Operations for the opening of the spinal canal have been all recommended in the sacro-coccygeal region, but in this region a gouge, chisel, and mallet are to be used instead of the bone-forceps. A long incision is made from below the twelfth rib, parallel to the median line of the sacrum ; the bone is chiselled through, and the anterior surface of the canal explored by means of the finger. The coccyx and lower part of the sacrum can be removed, piece by piece, using the .rongeur forceps. The lower three pairs of nerves may be sacrificed if necessary, but the upper sacral nerves supplying the pelvic organs must not be touched. The operation is a tedious one, and there is much oozing of blood. Removal of the Coccyx.—This operation is performed in obstinate cases of coccygodynia—i. e. painful or irritable coccyx. A median incis- ion is made, the bone exposed, and the articulation of the coccyx with the sacrum cut through. The plexus of veins immediately beneath the coccyx is to be avoided as well as the rectum. The bone can be removed subperiosteally. Vertebral Puncture.—This has been recommended by Quincke for the relief of pressure from an excess of cerebro-spinal fluid. A small trocar is thrust into the subdural space in the lumbo-sacral region, between the transverse arches or between the spinous processes of the adjacent vertebrae. In children the space between these parts of the adjacent vertebrae is comparatively large. The point of election is the third, fourth, or especially, the fifth, space in the lumbar region. The needle is directed toward the median line, entering outside of it—in children at the level of the space, and in adults at the tip of the spinous process. The first few drops of the fluid are slightly tinged with blood, but the remainder is clear. From 20 to 100 c. c. should be drawn oil* in an adult, and from 2 to 50 in a child. Rigid antiseptic precautions are necessary. The wound should be closed by iodoform collodion. 116 INJURIES AND SURGICAL DISEASES OF THE SPINE. Fiirbringer has tapped the vertebral canal in 86 cases, making the puncture in the second, third, or fourth intervertebral spaces in the lumbar part of the spine, using no anaesthetic, withdrawing as much as 110 c. c. of fluid in some cases: 37 of the cases were tubercular meningitis, and there Avas little benefit from the pro- cedure. In serous meningitis temporary improvement followed the puncture. The procedure does not appear to be injurious, but is only of temporary benefit. Tumors of the Spine. The spinal column may be attacked by malignant growths in the same way as are other tissues. These tumors are those which either originate in the bone-tissue of the spine or in the adjacent tissues (Plate VI.). Primary tumors of the spine are of the class which develop from connective tissue, such as fibroma, chondroma, myxoma, lipoma, sar- coma, and osteoma. Secondary tumors are those which come by meta- stasis, chiefly carcinoma, which is never primary. Osteomata usually arise in the periosteum, though exostoses may develop directly from the bone. Fibromata usually develop from the periosteum, and exceptionally from the marrow. Chondromata and myxomata develop either from the periosteum or the soft bony tissue. There are many varieties of sar- comata of the spine—central, small round-celled, and chondro-sarcomata. Angei- omata are very rare. Osteomata usually are solitary tumors, but others may develop in different foci. Diagnosis of tumors of the spine can only be made after they have become so extensive as to be felt on palpation, or to have caused enough destruction of bone-tissue to interfere with the erect position, or to press upon the spinal nerves or the cord, causing obstinate neuralgia and paralysis. The symptoms may resemble those of caries of the spine, and there may be a rounded projection of a few spinous processes. Caries of the spine is most commonly a disease of childhood, the reverse being true of tumors of the spine in most instances. Congenital Tumors of the Sacrum. In addition to the tumors classed as spinse bifidse, or congenital cysts, there is a rare class which consists of vestiges of an attached foetus. This varies greatly, from an ill-defined mass of tissue to a more or less completely developed structure like a dwarfed or deformed leg project- ing from the sacrum. This can be amputated unless so firmly united with the pelvis that such an undertaking would be fatal. ( Vide Vol. I. Chapter XXVI., Dermoids.) Sacro-coccygeal Tumors at the Junction op the Coccyx with the Sacrum. The most common form of these are varieties of spina bifida, already mentioned. They present themselves, however, in some instances slightly to the side of the median line. They are not always fluctuating, and may be dense, though it is characteristic of them that they vary in size from time to time. They are usually mistaken for fatty tumors, as in many instances they are covered by a thick layer of fat. Operative Sarcoma of the Spine and Cord. (Goldthwait.) PLATE VI. TUMORS OF THE SPINAL CORD. 117 interference with these cysts is too often fatal, owing to the difficulty of securing complete asepsis, from the constant escape of the cerebro-spinal fluid. Dermoid tumors originating in the embryonic remains of the post-anal gut have been already considered in Chapter XXVI. Vol. I. Of the various malignant growths which develop in the cord proper or its membranes, gliomata are the most commonly met, though fibrom- ata, sarcomata, glio-sarcomata, and angeio-sarcomata are all reported, but very rarely. Multiple fibromata have been observed simultaneously in the cord and the peripheral nerves. Fibromata are usually round, and give rise to more or less degeneration of the substance of the cord in their immediate vicinity. Gliomata constitute tumors of oblong shape. They are usually situated around the central canal. Their substance is sometimes firm, though usually delicate, and they frequently contain cavities. They are sometimes rich in vessels. Tumors of the Pia and Arachnoid.—Osteomata occasionally pre- sent themselves as small white disks. Angeiomata, from varicose enlarge- ment of the veins, sometimes exert pressure on the cord and nerve-roots. Tumors of connective-tissue origin may also be seen in the pia as primary affections, while secondary growths, carcinomata, may rarely be found. As tumors in the spinal canal are confined in an unresisting cavity, they are of importance even when small, and their early recog- nition is essential for successful surgical interference. The symptoms from tumors of the spinal cord vary greatly in their location, and according to whether they arise from the centre of the cord or from the dura and press upon the cord. Pain is usually present as an early symptom, but is not severe, and is frequently mistaken for rheumatism. This is accompanied by a certain amount of muscular or sensory paralysis. The pain increases pari passu with the tumor. It is rarely symmetrical, and in extradural tumors is always unilateral. Sometimes in tumors of the cord muscular spasm may be present in addition to pain, though this is a symptom which is more commonly seen in intradural growths. Horsley has called attention to the import- ance of the fact that the pain is not situated at a higher level than the tumor, and may be some distance below—a fact of importance in deter- mining the point of opening the spine in operation. Tenderness at the seat of the tumor is frequently present, but in the dorsal region the ten- derness is at a lower level than the tumor. Rigidity of the muscles of the spine may exist if the growth of the tumor cause irritation. Tumors of the Spinal Cord. Tumors growing in the cord present a gradual development of symptoms. There is first motor paralysis, later sensory paralysis preceded by pain. The pain is at first neuralgic and lancinating; anaesthesia and pain in the lower limbs ascend gradually from the feet toward the trunk, and there is a dull ache in a distinct portion of the spinal column, accompanied by weakness at that point, which is increased on fatigue. The reflexes, deep and superficial, are exagger- ated, and eventually lost, with symptoms of descending degeneration and wast- ing as the cord becomes diseased. The reflexes, as well as the pain and anaesthesia, begin in the plantar region and pass upward. The symptoms are not symmetrical, but are unilateral. Spasms and rigidity are present; the pupils are not affected. It should be borne in mind that there is a gradual loss of sensation or motion with intramedullary growths, while in the extramedullary growths the symptoms of 118 INJURIES AND SURGICAL DISEASES OF TIIE SPINE. pain and spasm indicative of irritation may precede the paralysis. If the paraly- sis be of gradual development, preceded by long-continued symptoms of nerve- irritation, beginning on one side and gradually transferred to the opposite side, a probable diagnosis of compression of the cord by a pressure outside the cord can be made. A diagnosis of the different varieties of tumor which may be de- veloped in the spinal canal is clinically impossible. For the surgeon it is necessary simply to determine whether there exist any pressure upon the cord, and if this pressure be external to the membrane and capable of surgical relief, or a growth of the cord itself and inoperable. The successful removal of tumors of the spinal cord belongs to the rarer feats of surgery, the difficulty lying not so much in the removal of the tumor as in the recognition of the affection at so early a stage that relief is possible. Chipault has collected 22 cases of operation on spinal tumors; Keen reports 3 more. The result of these operations was 11 deaths, 11 recoveries, and the result in 3 is uncertain. The operation is essentially a laminectomy, already described, plus the enu- cleation of the growth. CoCCYGODYNIA. This name is applied to a painful affection of the coccyx, which in some instances arises spontaneously, but frequently dates from an injury, such as a fall or a blow, or comes on after childbirth. It is almost entirely confined to women, and usually appears in persons of a neurotic tem- perament. In many instances an irregularity in the coccyx can be found on palpation. The treatment should be at first that which is found efficacious in neurasthenic patients—massage, electricity, and stimulants to the circu- lation, such as an application of heat and cold, besides general tonics ; in more obstinate cases removal of the coccyx is necessary. ( Vide Ope- rations upon the Spine.) SURGERY OF TIIE PERIPHERAL NERVOUS SYSTEM. Surgery of the Nerves. Most of the affections of the nervous system belong strictly to the domain of internal medicine. There are, however, certain diseases which should be considered, in part, in a surgical treatise, from the fact that they are relieved by surgical interference. These are divided as follows: I. Wounds and injuries to the nerves. IT. Diseased conditions calling for surgical interference, mainly— (1) Neuralgia; (2) Muscular spasm. Wounds and Injuries to the Nerves Contusions of the nerves are not uncommon, either in dislocation or fracture or from direct violence crushing the tissues. Constant pressure, WOUNDS AND INJURIES TO THE NERVES. 119 as in the use of crutches (“ crutch paralysis ”), or lying in a peculiar position with the arms under the head for a long period, as occasionally happens in intoxicated persons, sometimes produces changes which may be classed as injuries. An injury of the nerves is recognized from the resulting impairment in the function of the nerve—i. e. motor or sensory paralysis. All nerves are liable to injury, but lesions of a few nerves may be mentioned as not uncommon. The facial nerve is often injured in fractures, gunshot wounds, or incised wounds, operations for removal of tumors, and blows. This is easily recognized by the appearance of the face: the eyebrow cannot be raised nor the eyelids entirely closed ; the ala of the nostril on the paralyzed side does not move in res- piration, and control of the angle of the mouth is diminished; the patient cannot whistle ; the face on the paralyzed side is expressionless. The ulnar nerve is not infrequently divided above the wrist or at the elbow or in the upper arm. The flexor carpi ulnaris, the flexor profundus in its inner half in the forearm, and the whole group of the hypothenar muscles of the hand and the two ulnar lumbrical muscles, the interossei muscles, the adductor muscles of the thumb, and half of the flexor brevis pollicis are paralyzed. These muscles waste, and there is an atrophy of the hypothenar and a partial wasting of the thenar eminence. The position of the hand is characteristic, and what is termed a claw-hand results. The sensation following injury of the ulnar nerve varies. As a rule, the ulnar portion of the skin of the hand on the front and back, the little finger, and the ulnar half of the right finger are affected in injury to the ulnar nerve. The median nerve, when injured, is chiefly disturbed above the wrist. The motor symptoms of injury to the median nerve involve all the flexors and pronators of the arm except the flexor carpi nlnaris and the ulnar half of the flexor profundus. If the median nerve has been divided high up, there will be paralysis of the muscles of the thumb except the adductor and half, of the flexor brevis pollicis ; the hand can- not be pronated by muscular effort; flexion of the thumb is lost, and the thumb cannot be pressed to the other fingers. There is more wast- ing of the forearm than in ulnar paralysis. There is no atrophy of the hypothenar, but there is of the thenar eminence. The anaesthesia includes the radial half of the thumb and palmar surface of the index and middle fingers and the radial side of the right thumb. The radial nerve is rarely divided, and, as it is a sensory nerve, the sensation when the nerve is injured is imparted over the metacarpal bones and first pha- langes of the thumb and fore finger. The musculo-spiral nerve may be frequently injured in fractures of the upper arm or in gunshot wounds. The supinator longus muscle is paralyzed if the nerve be injured above the origin of this muscle, and wrist-drop results. The sciatic nerve is rarely injured except in gunshot wounds. The external pop- liteal branch has been divided in tenotomy of the hamstring muscles. If there be an injury to this branch, the anterior flexor muscles of the foot are injured, and foot- drop follows, the foot dragging when walking. If the sciatic nerve be divided or injured, all the leg muscles are paralyzed. The muscles of the thigh are not injured, and the patient can walk by throwing the leg from the hip forward. There is some impairment of sensation, but this is not as great as the loss of motion. There is loss of sensation in the foot and upper parts of the leg. Division and injury to the pneumoc/astric nerve are rare. A few instances have been reported, and in the removal of tumors of the neck the vagus has been injured in a few cases. Roswell Park has collected 50 cases of injuries to the pneumogastric during operations upon the neck, and finds that the statement in older writers that this is a fatal accident is not warranted by the facts. He also collected 15 cases of accidental injuries of the pneumogastric. The result in 2 is not known, but of the 13, 2 recovered. He concludes, therefore, that injuries to the 120 SURGERY OF THE PERIPHERAL NERVOUS SYSTEM. pneumogastric are not, as has been said, immediately fatal. Wyeth suggests that if the pneumogastric or hypoglossal or other important nerves be divided, they may be sutured immediately, and Bloodgood is reported to have successfully sutured the pneumogastric. In most of the reported cases, according to Park, there were no symptoms directly following division of the vagus. Cases of injury of the phrenic, however, are followed by severe dyspnoea, which in some instances is fatal. Neuralgia. The subject of neuralgia belongs properly to a medical rather than a surgical treatise, and this is also true in regard to the medical treat- ment. In some instances, however, neuralgia is due to peripheral irritation, compression, or degeneration, rather than central or con- stitutional causes, and surgical interference is justifiable for the pur- pose. Neurotomy, neurectomy, nerve-stretching, have all been employed for obstinate neuralgia, especially for the violent form of trifacial neuralgia. Division of the nerve (neurotomy) for neuralgia, as well as nerve- stretching, does not give as satisfactory results as excision of a portion of the trunk—neurectomy. In some instances of trifacial neuralgia a permanent cure results, and temporary relief follows this procedure in all suitable cases. Recurrence of pain is not infrequent, however, in the most obstinate cases, and recourse has repeatedly been had to removal of the Gasserian and other ganglia for relief. Muscular Spasm. Operations upon the peripheral nerves are sometimes necessary for the relief of muscular spasm. The particular affection for which neur- otomy, nerve-stretching, or, better, neurectomy, has been most often attempted is that spasm of the muscles of the neck known as spasmodic torticollis. Successful cases have been reported by Gairdner, Keen, Richardson, and others, but in some instances the operation affords little or no relief. Keen has recommended a division of the posterior cervical nerves on the opposite side, in addition to resection of the spinal acces- sory on one side. This has been done by the operators mentioned, and with success in some instances. Operative interference should not be considered until after a thorough trial of all other measures. Of these, a complete rest of the muscles from the labor of supporting the head is of importance. Fixation of the head by a plaster bandage holding head and thorax, recumbency with light traction applied as in cervical caries, accompanied by massage and graduated muscular exercises, carefully prescribed and thoroughly carried out, present a rational form of treatment which is sometimes successful if persisted in for a long period. Mechanical appliances are of temporary assistance. A few instances have been reported by the use of conium, atropine, and gelsemium. In case of failure of all other measures, neurectomy of the spinal accessory, and, if necessary, of the posterior cervical nerves, gives some promise of success. OPERA TIONS UPON NERVES. 121 Operations upon Nerves. The operations upon nerves are nerve-suture, nerve-grafting, nerve- stretching, division of nerves, and excision of parts of nerve-trunks. Nerve-suture.—Nerves should be sutured as soon as they are divided, if that be feasible (primary suture), even if the nerve be only partially divided. Two or three sutures are passed, not only through the sheath of the nerve, but also, if necessary, through the nerve itself, avoiding twisting the nerve-fibres. Fine catgut or silk should be used and a round needle. Fixation of the limb on a splint is advisable after nerve-suture in order that the sewn nerve should not bo torn apart on motion. If there be separation of the ends of the nerves, they can be approximated by stretching, with fixation of the limb in such position as best to relax them. Suture can be also attempted weeks or months after the injury (secondary suture); the proximate end is ordinarily easily found from its bulbous termination, but the distal end is not so easily discovered. Recovery with restoration of function takes place in two-thirds of the cases operated upon. In 84 cases of primary suture reported by Howell and Huber, 42 per cent, were successful. In secondary suture the same writers report, in 80 cases, 38 per cent, of successes, 12 per cent, of failures, 50 per cent, with improvement. Nerve-grafting.—Experiments have been tried in grafting nerves where the gap between the ends from a loss of the nerve-substance is so extensive that the ends cannot be approximated even by stretching. Reported cases of success by this method have been reported when the sciatic nerve of a dog has been used. Nerve-stretching or Elongation.—A nerve can be stretched one- twentieth of its length. The amount of resistance to stretching is greater than would be imagined. The sciatic does not break under a strain of less than 80 pounds; 6 pounds’ pull is necessary to break the supraorbital nerve, according to Marshall. The amount of force required is greater in living than in dead subjects. The facial nerve will bear a strain of from 5 to 7 pounds, so that the head can almost be lifted from the table without a rupture of the nerve-trunk. The theory as to the benefit of nerve-stretching is that changes in nutrition follow, while adhesions to the neighboring parts or to the sheath are destroyed. Nerve-stretching is done by exposing the nerve and loosening it from the surrounding tissues: it is then stretched by hook- ing it under the thumb, or in some nerves, as the seventh, by a button- hook. Nerve-stretching by what has been called the bloodless method has been employed on the sciatic nerve. This consists in flexing the thigh forcibly upon the trunk, the leg being kept straight at the knee while the patient is under an anaesthetic. The method lacks surgical pre- cision, although some cases have been reported where benefit has fol- lowed. Nerve-stretching has been used in certain cases of spasm of the facial muscles and in wry neck, but the benefit of this procedure is usu- ally only temporary. Neuroplastic Surgery.—This has been advocated as a substitute for nerve-grafting. A portion of the severed nerve at each of the cut ends is split and freed nearly to the termination; these strips of nerve are folded over and their unattached ends stitched together. This method is as yet in an experimental stage. 122 SURGERY OF THE PERIPHERAL NERVOUS SYSTEM. Operative Details. The operative details for the finding and resection of the different nerves require especial attention in each individual case. The few fol- lowing facts are to be borne in mind by the surgeon in considering ope- rations upon the nerves and nerve-structures most commonly attacked : The Supraorbital Nerve.—A curved incision, an inch in length, is made across the orbital notch, which can usually be felt. The incision can be made in the eyebrow and the scar will be hidden by the hair. The Division of the Fifth Nerve at the Superior Maxilla.—The infra- orbital nerve comes to the surface at the infraorbital foramen. This is found at the intersection of a line drawn from the superior orbital notch downward between the two lower bicuspid teeth. A curved incision one and a half inches long is made just below the lower border of the eye: where this incision meets the line already mentioned the nerve will be found. It lies under the levator labii supe- rioris. The nerve can be lifted from its bed by a hook and dissected as far back as the orbit. A pull upon the nerve will remove nearly the whole of it. The Removal of Meckel’s Ganglion.—This ganglion can be reached by Chavasse’s modification of Carnochan’s method. This consists of an incision below the eye, T-shaped, the cross portion reaching from one corner of the eye to the other, and the upright nearly to the mouth. The infraorbital nerve is found and tied with a piece of silk. The antrum is opened by means of a trephine or chisel: a trephine is applied to the posterior wall of the antrum; the nerve is then drawn down after being divided from the cheek, and will serve as a guide to the ganglion, being pulled into the spheno-maxillary fossa of the foramen rotun- dum. Horsley does not trephine the antrum, but lifts the floor of the orbit, including the periosteum, and opens the canal by means of a sharp-pointed bone-forceps, and follows the nerve to the foramen rotundum. Luecke resects the zygoma, turns the temporal muscles up, and makes an opening for the ganglion. Inferior Dental.—This nerve can be reached in several ways. An incision two inches long is made along the lower border of the jaw; the flap is pushed upward, the masseter muscle being separated from the jaw, and a trephine is applied one and a quarter inches above the angle of the jaw. The nerve is then exposed. Removal of the Gasserian Ganglion.—The removal of this ganglion has been done in cases where the ordinary neurectomy has not given relief. This ganglion is removed in the following manner: The eyelids are sewn together for three days in order to protect the eyeball; a curved incision is made half an inch below the external angular process of the orbit, along the zygoma, to its posterior end, then downward to the angle of the jaw, and finally along the lower border of the jaw as far as the facial artery. This flap is brought forward; the zygoma is first divided and turned downward with the attachments of the masseter muscles; the coronoid process is divided and brought upward with the attachment of the temporal muscle. The internal maxillary artery may be ligated and the external pterygoid separated from the sphenoid and the external pterygoid plate. A half- inch trephine is applied in front and slightly to the outside of the foramen ovale, with the edge of the trephine just touching the foramen ovale. There is usually considerable hemorrhage. A strong light is advisable. In the first instance the eye was destroyed, and had to be removed. In later cases, however, this has not been the result. Mr. Horsley, instead of attempting to remove the entire ganglion, which he says cannot be done without opening the cavernous sinus, trephines and removes the squamous portion of the temporal bone, opens the dura, ligates the middle meningeal, lifts up the brain, and exposes the roots of the nerve as they pass to the Gasserian ganglion. These lie in a canal a quarter of an inch in diam- eter beneath the tentorium, which should be opened. The nerve-roots are cut and drawn away from the pons. This operation has never been done but once, and then with a fatal result. Mixter has resected the second and third divisions at both the foramen rotundum and ovale, and has done the operation successfully several times. He makes an incision similar to that for removal of the Gasserian ganglion. The temporal and pterygoid muscles are separated and turned down, using an incision which has been described by Salzer. OPERATIVE DETAILS. 123 Park has advised a preliminary ligation of the common carotid as a great help, no matter which method of attack be selected. Lingual Nerve.—This has been operated on to diminish pain in cancer of the tongue. The nerve lies on the floor of the mouth beneath the mucous mem- brane, and can be felt if the tongue be forcibly stretched. The mucous membrane is incised and a hook is passed under the nerve. The nerve can also be found as it lies in the tongue close to the first molar of the lower jaw. Fig. 51. Exposure of Meckel’s or the Gasserian ganglion (Krause). Fragment removed from the fifth nerve. The Seventh Nerve.—This nerve is reached by a vertical incision two and a half inches long made behind the ear: the parotid is found at its posterior limit and is turned forward; the sterno-cleido insertion is then found, and in the space between these two landmarks the prevertical muscles will be found. The inferior branch lies in front of the fasciae covering these muscles, and crosses both the mastoid and the vertical ramus of the jaw. This nerve can also be found by an incision in front of the ear: one of the main branches is found in the parotid gland, and is followed back until the main trunk is reached. Spinal Accessory Nerve.—This nerve is divided and excised for spasmodic 124 SURGERY OF THE PERIPHERAL NERVOUS SYSTEM. wry neck. It may be reached anterior to the sterno-cleido-mastoid, an incision being made along the anterior body of the muscle, passing two inches downward from the lobe of the ear. The muscle is turned to the outside, and the nerve can be found a little above the level of the hyoid bone. If it be desired to reach the nerve, as it is possible, from the sterno-cleido-mastoid, the incision is made along the outer border of the muscle, the centre of the incision being the centre of the muscle. The nerve will be found a little above this point. Division of the Nerves in the Deep Posterior Cervical Plexus.—Keen divides the posterior branches of the first, second, and third cervical nerves in spasmodic torticollis which has been unrelieved by the incision of the spinal accessory. A transverse incision is made half an inch below the level of the lobule of the ear. The trapezius muscle is divided in the same line. The muscle is then dissected up and the great occipital nerve is found. The complexus is then divided, and the great occipital nerve is followed until its origin from the posterior division is reached. The suboccipital or first cervical nerve is excised. It lies in the tri- angle close to the occiput formed by the two oblique muscles and the posterior straight muscle. The exterior branch of the posterior division of the cervical nerve is found lower down, and should be divided close to the bifurcation of the main nerve. The anterior branches of the cervical plexus may be reached by means of an incision along the posterior border of the sterno-cleido-mastoid muscle. The Brachial Plexus.j—An incision is made above the clavicle similar to that which is used for the ligation of the subclavian artery. The deep fascia is opened and the nerves will be found. Median Nerve.—The same incision is used as for the ligature of the brachial artery. The nerve lies in front of the artery and passes from within outward. The median nerve can be reached in the forearm or the wrist. An incision two inches long is made on the inner side of the tendon of the palmaris longus. The nerve lies underneath the deep fasciae. The branches of the median nerve to the thumb and fingers can be reached by an incision along the lower inferior border of the thenar eminence underneath the palmar fascia. Ulnar Nerve.—An incision is made similar to that for the finding of the median nerve. The nerve lies farther back. It can be exposed behind the elbow, using an incision between the internal condyle and the olecranon. At the wrist an incision on the radial side of the tendon of the carpi ulnaris exposes the nerve, which lies under the deep fasciae. The Musculo-spiral Nerve.—An incision is made between the biceps and the triceps muscles. The deep fascia is opened, and the nerve is found in a groove in the interspace between the two heads of the triceps. The Radial Nerve.—A longitudinal incision is made on the outer border of the forearm three inches above the wrist-joint. The Great Sciatic Nerve.—An incision is made, four inches long, in the middle line of the thigh, beginning below the gluteo-femoral crease. The deep fascia is cut, the biceps is found, and the sciatic nerve will be seen at the outer border of the muscle. Tibial Nerves.—The anterior and posterior tibial nerves are found through the same incisions that are required for ligation of the arteries. Intraspinal Division of the Posterior Nerve-roots.—This ope- ration has been done by Abbe in a case of inveterate neuralgia. Half of the arch of the fourth and the whole of the fifth, sixth, and seventh cervical arches were removed by Abbe in his first case. The dura was exposed, and the sixth and seventh cervical nerves were divided between the dura and the bone. Temporary relief followed. The operation has also been done by Horsley and others. It is more serious than opera- tions on the peripheral nerves, and the results do not seem to be any more favorable. Nerve-tissue maybe involved in malignant growths developed in the surrounding tissues, but primary malignant tumors of the nerves are rare : Tumors op the Nerves. TUMORS AND DISLOCATIONS OF THE NERVES. 125 they are sarcomata or gliomata. (Vide Vol. I. Chapter XXVI.) The term neuromata, a general one applied to enlargements observed in nerves, is unfortunate. The most common form of* the neuroma is seen, after amputation, in the bulbous enlargements of nerve-ends which are involved in the surrounding tissue, though this can be more or less readily differentiated. A tumor may occasionally appear in the course of a nerve without apparent external irritation. This is due to an increase of the connective tissue which arises from the endoneurium, though sometimes from the perineurium, the axis-cylinder being there surrounded or its fibres pressed upon by the growth. These, are in fact, fibromata of the nerves. They are usually multiple and limited to cer- tain nerve-tracts. Sometimes these tumors are sessile, and sometimes they have a pedicle. They may be found in the nerves of the skin, and are sometimes called fibromata of the skin. In very rare instances they may attain considerable size, even being reported as large as the fist. Plexiform neuromata consist of a thickened mass of nerve-fibres resem- bling somewhat a plexus of veins. The nerve-fibres are elongated and tortuous and increased in numbers. These form true neuromata, and may be found in the head or in any part of the body. Dislocation of the Nerves. Dislocation of nerves has been reported in a few instances. This is easily recognized by a movable cord which is felt under the skin, and by a sensation which the patient notices when this is pressed upon. Where no other means alfords relief it is possible to cut down upon the the nerve and excise a portion, if it be not possible by section and suture to restore it to its place. Dislocation is most common in connection with the ulnar nerve at its passage back of the inner condyle. CHAPTER III. SURGICAL DISEASES AND INJURIES OF THE HEART AND PERICARDIUM, WITH SURGERY OF THE LARGE BLOOD- VESSELS; LIGATIONS. Duncan Eve, M. D. Malformations of the heart are, fortunately, of rare occurrence, for the most part represent survivals of foetal conditions, and pertain more to the domain of teratology than surgery, except as curiosities. Absence of the pericardium, still more rare, is mostly associated with misplacement of the heart, and must not be confused with adhesion of the pericardium and consequent obliteration of the sac, which is so fre- quent in after-life. The acardiac foetus can profit nothing at the hands of the most skilful surgeon; the defective arrangement of the valves and openings of the heart, limited entirely to a perpetuation of the con- ditions of foetal life, is solely within the domain of pediatrics; and thoracic fissures (fissura sterni) resolve themselves into those in which, besides the sternum, the skin is also separated, in which case the heart is exposed (cardiac prolapse), and those in which the integument is not cleft, and when the heart is covered by it (cardiac hernia) are left to the ingenuity and originality of plastic surgery, which alone can determine the best mode of procedure. Misplacement of the heart (situs mutatus) is also of rare occurrence con- genitally, and the more important cases are merely a part of a general malformation of the body. The heart may be transposed, occupying a position on the right side of the chest; with this there is usually a trans- position of other viscera, though it sometimes occurs alone. Or it may occupy the middle line, retaining permanently its position in early foetal life. Misplacements from pathological conditions of other viscera and structures are more frequent. Thus the heart may be pushed down lower than normal by aneurisms of the aortic arch or the large vessels at the root of the neck or morbid growths occupying the upper mediastinum; it may be pushed too far to the left or right by pleuritic effusions or col- lapse of one or other lung; or it may be pushed too high up by abdom- inal growths or adjacent visceral hypertrophy, fluid accumulations, or gaseous development, the latter producing the greatest degree of dis- placement. These are all to be watched for by the surgeon in operations on the heart or adjacent structures, and with an ordinary knowledge of percussion and auscultation are readily detected, needing only bare men- tion here by way of precaution. The history of the case and a careful examination of the heart itself and adjacent structures generally suffice for a solution of the existing condition and its cause. 126 WOUNDS AND INJURIES OF THE HEART AND PERICARDIUM. 127 Wounds and injuries of the heart and pericardium have been, and are likely to be, of only too frequent occurrence. The well-known site of the heart has made it only too accessible to the death-dealing instrument of the suicide or assassin ; its feebly protective surroundings, especially in front, leave it only too approachable to sword-thrust, bayonet, or bullet on the battle-field, or missiles and fragments projected by inten- tional or unavoidable and accidental force. Most generally, the excep- tions being few and far between, lesions of any magnitude—and some quite slight ones, indeed—have and will prove fatal. Yet the history of the past has shown quite a number of slight and some severe wounds that have not been immediately lethal, and yet a few where life was pro- longed indefinitely or determined by some altogether different cause. The number of favorable results in such lesions have been largely added to in the last thirty years, and it is to be hoped will yet be still more largely increased. In “ A Collection of Remarkable Cases in Surgery,”1 made by my father, the late Prof. Paul F. Eve, M. D., nearly forty years ago, he collated from various authentic sources twenty cases of wounds of the heart, produced by various instru- ments and missiles ranging all the way from the musket-ball to a large sewing- needle, which may be briefly summarized as follows: 1. Mr. Lees (Dublin Journ. Med. Sciences, 1837). A pistol loaded only with powder, placed directly against the chest at apex of the heart; great depression, anxiety, sense of weight about the heart, tendency to fainting and severe palpita- tion, with recovery in a few days. 2. E. R. Maxson (in Buffalo Med. Journ., 1831). Rupture of right auricle from lifting heavy weight; walked about the house the two following days ; slight symptoms of dizziness at close of second day; on retiring to rest became thirsty, called for drink, and immediately died. Autopsy showed the rupture large enough to admit a crow-quill, and pericardium distended with coagulated blood. 3. J. H. McNicoll (in Lancet, 1852). Rupture of heart on getting up too soon after delivery; death in a short time—about half an hour. 4. Case of Due de Berri. Opening of ventricle by dagger; Dupuytren in attend- ance, who kept the wound open ; patient lived several hours. 5. Charles E. Lavender, M. D., report to Med. Ass’n of Alabama. Right ven- tricle penetrated by blade of knife; complete recovery—a most remarkable case, in which the rest treatment was faithfully carried out (1850), 6. Mr. Lees (Dublin Journ. Med. Sciences). End of sword passing through right auricle; death on second day. 7. Ibid. Wound of heart by fractured rib ; death after some hours. 8. Ibid. Heart transfixed by iron stilet; patient lived twenty hours. 9. J. L. O’Connor, M. D. (London Med. Gazette, 1821). The heart transfixed by a darning-needle in an attempt at suicide; recovery. 10. Dr. Renauldin and M. Boujet (in Patterson’s Med. Register). Death from pericarditis due to a needle introduced (suicidal) into the heart five days previ- ously. 11. M. Trelat (Bull. g&n. Th'er., 1846). A large needle removed from the heart after three days’ sojourn in it without ill consequences; needle two inches long, and oxidized when removed. 12. J. McNeill, M. D. (Med. Exam., 1849). Needle found in the heart upon dissection; had evidently been there more than a year. 13. Thomas Dorris, M. D. (Am. Journ. Med. Sciences, 1834). Lacerated wound of the heart by a fragment of wood; healing of wound; death on thirty-seventh day. 14. Lancet, 1846. A very important case reported by Mr. Holmes, in which the anterior wall of right ventricle was opened by a linear wound (gunshot) without perforation of pericardium; death soon after. 1 Eve’s Surgical Cases, 8vo, p. 858, 1857, J. B. Lippincott & Co. 128 SURGICAL DISEASES AND INJURIES OF THE HEART. 15. L. Randall, M. D. (Am. Journ. Med. Sciences, 1829). Death sixty-seven days after gunshot wound from fowling-piece, three small shot found in right ven- tricle and two in right auricle. 16. Dr. A. Christison (in Edin. Monthly Journ. and Rankin’s Abstract, 1853). A gunshot wound one inch outside of left coracoid process, passing downward into the thorax, received April 14th; death at the end of June following, and musket- ball found in left ventricle at apex, partly covered by a layer of white lymph. 17. Schmidt’s Jarbuch. and Br. and Foreign Med.-Chir. Rev., 1852. A ball found in right ventricle, having dropped down into it through pulmonary artery; death twenty minutes after reception of wound. 18. Dr. Latour. A soldier shot in the chest; great hemorrhage, which grad- ually subsided; wound cicatrized at end of three months, after which no incon- venience other than palpitations for three years; death six years after reception of wound, not due to palpitations; the ball was found in the right ventricle near its point, lying on the septum medium. 19. Dr. Finnell, N. J. {Med. Reporter, June, 1855). The prize-fighter Poole in a pugilistic encounter with Baker was shot with a revolver, and so far recovered that he wanted to renew his encounter on the fourth day afterward. Death twelve days later; ball found lodged in the septum between the ventricles, about one and a half inches from the apex of heart, and one-fourth of an inch from its surface. 20. Dr. M. Marini {J\ded. Examiner, 1844). The left ventricle opened by a dagger; death nine weeks afterward. In addition eight other cases are cited in which the cavities of the heart were penetrated by bullet, 1; stab with sharp instrument, 3; heart transfixed entirely, 1 ; needle, 1; piece of ramrod, 1; bayonet, 1—the individuals dying at different inter- vals varying from nine hours to sixty-six days. Since this “ Collection ” was made quite a number of cases have been reported by various observers in which life has been prolonged from a few hours to days, weeks, months, and even years. Fischer collected 452 cases of heart-wounds in which death occurred in two or three minutes after the injury in about one-fifth of the cases, and 72 recovered; the diagnosis in 88 verified by subsequent post-mor- tem, death being from other causes. Wounds and injuries of the heart produce deatli by—1, hemor- rhage ; 2, shock ; 3, arrest of the heart’s action by the accumulation of blood in the pericardium or around the heart in the thoracic cavity; 4, by inflammation, suppuration, or sequelae due to the subsequent progress of the wound, lesions set up thereby, or induced by the character of the injury and the instrument producing it. The danger is greater and more imminent by reason of the character of instrument producing the wound, and stands in the following order: (o) contused and lacerated wounds, such as gunshot wounds, those produced by blunt and irregular instru- ments, etc., and punctured wounds if the instrument is of large si/e; (b) incised wounds; (c) punctured wounds made by small instruments. In most instances the hemorrhage in contused and lacerated wounds will be so severe as to cause death almost immediately; and shock, exces- sive inflammatory, suppurative, and other sequelae are more certain to supervene. Incised'wounds are not always attended by immediate alarm- ing or serious hemorrhage, and shock may be at first slight. A thin, narrow blade transfixing the muscular walls makes a valve-like opening by means of the interlacing muscular fibres; severing some, it passes between others; while shock is also apt to be slight. A greater danger is from the accumulation of the blood around the heart, impeding or arresting its action. Punctured wounds are likely to be attended with shock, hemorrhage, and subsequent developments in proportion to the si/e of the agents by which they are produced. The evidence of wounds of the heart may be summarized as follows : character, site, course, and nature of instrument producing the wound, WOUNDS AND INJURIES OF THE HEART. 129 together with certain phenomena referred to the heart itself, as a systolic bellows-sound, a peculiar tremor about the heart, with small, intermit- tent pulse, an undulating crepitation and bruit, and such phenomena as can be obtained by careful auscultation and percussion. Dulness upon percussion over an increased and increasing area, syncope, precordial anxiety and dyspnoea, diminished impulse of the heart, and pain may be suggestive when present. Treatment.—The patient should at once be placed in the recumbent position and kept there, with head low and every possible movement prevented. If he has to be moved, it must be done with the greatest care and caution to prevent any undue movement of the body, and should be preceded by a full dose of morphia hypodermically. Nar- cosis as deep as may be considered safe should be maintained for some days—at least until all danger from shock and hemorrhage is considered past. Thirst should be prevented so far as possible, and nutrition maintained rather by copious enemata of fluids and semi-fluids than by the mouth, the act of deglutition, even of fluids, having the elfeet of increasing the heart’s action, which is to be avoided as adding to the danger from hemorrhage. Digitalis should not be given, nor stimulants; far better will be found veratrum and other cardiac sedatives: to dimin- ish as much as possible the heart’s action is of the greatest importance. So long as the heart’s action seems to be maintained to a reasonable degree, only the simplest antiseptic dressings to the external wound are called for. A flannel bandage applied as tightly as consistent with comfortable respiratory movement should be early applied and main- tained in position. Over this an ice-bag or cold applications, rapidly evaporating lotions if the ice-bag seems to disturb the patient by its weight, or cold cloths frequently reapplied. The strictest quiet of sur- roundings and of the patient’s mental condition is imperative. If life be maintained for twelve to twenty hours or more, and a care- ful examination, which should be made at frequent intervals without disturbing the patient, shows that the heart’s action is becoming impeded by the pressure of extravasated blood around it, manifested by more feeble pulse and heart-sounds, cyanosis, dyspnoea, etc., then comes the propriety of opening the chest and pericardium, removing clots and blood by washing out with warm water thoroughly sterilized or other means. This may be done by simple incision between the fourth and fifth ribs on the left side, if other location is not indicated by the cha- racter of the wound, or by excising the cartilages of one or more ribs. An incision a few lines within the border of the sternum parallel with the lower border of the fifth rib or lower, extending outwardly about one and a half or two inches or more, is made; then a similar one parallel with the upper border of the fourth or third rib, or higher if deemed necessary, connecting the two by a transverse incision about the centre and turning the flaps well back. The costal cartilages, having been separated from the sternum, may be elevated, and the ribs or their car- tilages severed at a point distant enough from the sternum to give sufficient room. The internal mammary artery may have to be secured, as well as the intercostals. Pushing the pleura to one side (if this has not been done by the distended pericardium), the pericardium can be opened to such an extent transversely or longitudinally as may be 130 SURGICAL DISEASES AND INJURIES OF THE HEART. deemed advisable. Gussenbauer performed this operation satisfactorily for purulent pericarditis after the above method. The site chosen is the one of election. The following is a brief synopsis of a case reported by H. C. Dalton, M. D., of St. Louis in 1894 : “ A man in a fight was stabbed over the left breast; the wound was an inch in length and an inch and a half above the left nipple. There was little hemorrhage from the wound, and normal cardiac dulness was found on percussion. The percussion of the chest showed absence of dulness. The wound was closed and antiseptic dressings applied. Ten hours after admission to the hospital percussion revealed dulness over the entire left side, and much pain was com- plained of. The patient was removed to the operating theatre and the dressings taken off, when it was found that blood and air gushed from the wound with each inspiration. An incision was accordingly made, eight inches in length, over and parallel to the fourth rib, and six inches of the rib resected. The intercostal artery having been tied, the pleural cavity was found full of clotted and fluid blood, which with each inspiration poured from the wound with great force. The patient was turned on his left side, and with a long pair of forceps, armed with a sponge, the pleural cavity was cleansed of blood. Subsequently it was discovered that a transverse wound of the pericardium existed to the extent of two inches, and steps were taken to suture the lesion. In carrying out this procedure great difficulty was experienced, owing to the pulsation—at the rate of 140 per minute—of the heart. The peri- cardium with each pulsation of the heart rose and fell, and, in order to carry into effect that which was being attempted, it was necessary to follow the movements of the organ. Ultimately, a continuous suture of catgut was satisfactorily inserted in the wounded pericardium; the pleural cavity was then thoroughly irrigated with sterilized warm water, the external wound closed, without a drainage-tube, and antiseptic dressing applied. It may be noted that at several stages of the opera- tion, which lasted an hour, the patient seemed to be dying, and in order to avert collapse hypodermic injections of whiskey and strychnia were resorted to. Before the pericardial wound was sutured, examination of the heart was made with a view to the discovery of a wound in the organ, but no lesion was found. The patient made an uninterrupted recovery.” Thirteen years ago Dr. Block of Strasburg pointed out that death in cases of heart-wounds resulted, as a rule, from hemorrhage, not shock, and that sufficient time was often given for suture, which his experi- ments on dogs showed was possible. De Vecchio made a similar report at the last International Medical Congress at Rome, 1895. These are the general outlines suggested; it may be necessary to vary them in any particular case: First, regard the most imminent danger and ward it off—by passive measures if possible, and, if they seem to be ineffectual, resort to active ones, always keeping within the lines of reason and a correct knowledge of the situation. Should it become necessary, as I believe it to be possible, to suture a wound in the heart-walls, interrupted sutures closely applied, made of thoroughly aseptic animal tissue, should be used; so also in closing the wound in the pericardium. While aseptic silk will be encysted, PARACENTESIS OF THE PERICARDIUM. 131 here we want absorption of the suture, which will not be necessary to remain very long: forty-eight hours will amply suffice for adhesion in so vascular an area. Park has shown the success of this measure in dogs. Paracentesis of the heart, or cardicentesis, may be neces- sary in cases of engorgement of the right cavities from pulmonary disease where death from dyspnoea is imminent from the overtaxed con- dition of the heart. While it should never be resorted to so long as other measures hold out any hope, death should at least be held at bay as long as possible by resort to this operation, and a successful issue may result. It is a well-attested fact that the introduction of a small, aseptic aspirator or other needle into and through the heart-walls has produced no material injury of this organ. Of the two cavities of the right heart, I would prefer the ventricle, by reason of its thicker walls. Introducing the needle into the space just above the fourth rib, about one inch to the right of the sternum, and pushing it backward, inward, and slightly downward, or going in just above the fifth rib and pushing it directly backward and inward, the right ventricle may be reached—the only precautions being that the aspirator be in good working order and the needle thoroughly aseptic, as should be the site of puncture as well as the operator’s hands. From three to six or more ounces of blood may be withdrawn as the exigen- cies of the case may require. Dr. G. C. Cottam of Pock Rapids, Iowa, has reported a case in which he, in his efforts to reach the right auricle through the sixth interspace, tapped the left ventricle: the result was, however, satisfactory, as his patient, who was in an advanced stage of incipient phthisis and at the point of death, lived six weeks longer, and was far more comfortable, death being due to exhaustion. Dr. Allan D. Sloan has reported a case in which he plunged a trocar attached to an aspirator directly into the right side of the heart, through which some eight ounces of blood flowed. This happened in the case of a woman suffer- ing from pericarditis with effusion. The woman was apparently dead from heart failure, its action having ceased, and a hurried attempt was made to evacuate the fluid with the above result. He supposed when the blood flowed that the woman would die from the heart injuries. However, the cannula was withdrawn a little, the fluid evacuated, and, to the doctor’s surprise, the heart began to beat again, and after an hour or two the patient regained consciousness; two months later she was sent to the country, and four months later was reported as being perfectly well. Park has even tapped an abscess in the heart-wall. Numerous other cases might be cited from the literature of the past, but these, the most recent, are deemed sufficient. Paracentesis of the pericardium is now a well-known pro- cedure, though not so frequently resorted to as it should be, notwith- standing the valuable addition to its literature made by Prof. John B. Roberts, M. I)., of Philadelphia, in his most excellent monograph. Paracentesis should unhesitatingly be resorted to whenever life is in danger from distention of the sac by an effusion of any extent, no matter what the amount of the effusion or the cause of the disease may be. Roberts says : “ Whenever the effusion, whether it be serum, pus, or blood, accumulates so rapidly or in such quantity that it threat- ens to destroy life and refuses to undergo absorption by ordinary treat- ment, it is the duty of the attendant to tap the distended sac.” Given an excess of fluid in the pericardium, great or small, and a manifesta- 132 SURGICAL DISEASES AND INJURIES OF THE HEART. tion of failure of the vital powers not due to other well-defined causes, indicated by feeble cardiac action, ill-defined and weak heart-sounds, thready and flickering pulse, cyanosis, dyspnoea, orthopnoea, etc., then we do not hesitate to use the aspirator any longer than to take timely and necessary precautions that have already been suggested in tapping the heart—viz. a good working instrument, small needle, and strict asepsis. The point to be selected is preferably in the fourth or fifth left inter- costal space, about two to two and a quarter inches to the left of the median line of the sternum, entering rather nearer to the upper edge of the lower rib bounding the space, pressing the needle backward and slightly inward until the sense of resistance is no longer felt by reason of the needle entering the sac or the fluid appears in the outflow tube. The patient should be as nearly recumbent as possible, to allow the heart to fall back from the anterior wall of the sac. Should the sac refill, it can be again emptied, and in the event that pus, and not serum, in a first or subsequent aspiration appears in the outflow, there is nothing to be done when the sac fills again, as it surely will, but open incision1 and thorough drainage, as in a case of empyema of the pleura. Care should be taken in the introduction of the needle, and a just estimate made as to the depth at which the heart will be found: this reached and no evi- dence of having gained access to the sac existing, the needle had better be withdrawn slightly and pushed forward in a little different direction again, or another site tried. If the cartilage is perforated, a disk may Fig. 52. block the lumen of the needle and cause error; this will not occur, however, if the H. Landis Getz trocar and cannula be used, which are by far the best if those small enough can be secured, as after the trocar is withdra\ u a rounded and not a sharp point is left to come in contact with the heart-wall as the effusion escapes. The Fitch dome trocar, if of small size, is also a very suitable instrument, as is the one suggested by Roberts. If, after the second or third evacuation of a serous exudation, the sac again till, the injection into the sac of a solution of iodine (tr. iodini, 3 fluid drachms; potas. iodidi, 20 grains; aq. dest., 10 fluid drachms) has been proven to be both applicable and successful. Quite a number of able authorities have advised other points than the one suggested, which is the one preferred by Roberts, and which I deem the most suitable, except in cases in which a bulging of an inter- costal space or at some other point may indicate that the fluid can be more easily reached. Roteh of Harvard University advises the fifth right interspace as being the most accessible, and with less danger of puncturing the over- Small trocar and cannula—can be used with or without aspirator. 1 First practised by Romero in 1801, afterward by Rosenstein and others. LIGATION OF ARTERIES. 133 lying pleura than the left side. His observations possibly having been made on children, the heart is more likely to be found nearer the central line than in adults. Professor O. H. Wilson, M. I)., of Vanderbilt Uni- versity, however, has reported a successful case of tapping in the posi- tion recommended by Ilotch in an adult. Ebstein of Gottingen also reports a similar case. In purulent pericarditis, which cannot be definitely diagnosed until the character of the fluid is open to ocular inspection, there is only one course of procedure. It has been thought that a purulent effusion would be indicated by a greater degree of severity in the clinical phenomena, greater depression, a lower state of health, more feeble cardiac and pulse movement, etc. But there is no satisfactory and reliable evidence other than the fluid itself: this may be obtained by a long needle attached to an ordinary hypodermic syringe. When we are satisfied that there is pus within the pericardium, it should be thoroughly evacuated by a free incision, a drainage-tube inserted, and, if thought necessary, the cavity washed out with a warm (100° to 105° F.) mild antiseptic solution. Or it may be well enough, in order to secure thorough drainage, to remove a section of one or more ribs, which will be advisable in some cases. A case reported recently by Eiselberg in Wiener Min. Wocli. is of special importance, it being that of a boy of seventeen who developed purulent pericar- ditis after a stab wound of the pericardium. Puncture of the pericardium having been performed several times without relief, incision was determined on. The cartilage of the fourth rib on the left was resected, and the thickened pericardium exposed. After exploratory puncture it was opened by a transverse incision 4 cm. in length, and 2 litres of sero-purulent fluid were evacuated. The cavity was washed out with warm water, salicylated, the borders of the pericardial incision stitched to those of the wound, and two drainage-tubes inserted. Complete recovery took place in four weeks. Eiselsberg insists upon the importance of suturing the pericardium to the lips of the wound to prevent infection of the pleura. In cases of hydropericardium due to renal disease or other cause than pericarditis I would prefer an open incision and drainage rather than repeated tapping. Ligation of Arteries. The ligation of arteries is resorted to for the control of hemorrhage, the cure of aneurisms, the arrest of the growth of inoperable tumors, and the relief of hospital gangrene. While the necessities of the ease may require any point to be selected, the operations here given are at the site of election, and may have to be materially modified to meet the exigencies of the occasion. The essentials are a correct knowledge of the anatomy of the part and the principles of modern or aseptic surgery. It is not essential in all cases, as was taught by Celsus and others in his day, to use two ligatures, dividing the vessel between them, one ligature usually sufficing, leaving the artery undivided, as in the event of secondary hemorrhage at the site of the operation the vessel will again be more readily found. Nor is it necessary in using the aseptic ligature to tie the artery so tight as to divide the internal and middle coats, but only to press the opposing surfaces together temporarily to secure obliteration of its canal. The intima becomes covered with 134 SURGICAL DISEASES AND INJURIES OF THE HEART. granulations, developed from it and the clot that forms at the point of arrest of the circulation, which, uniting, form a firm union ; also plastic matter forms around the ligature, absorbing it if of animal tissue or encysting it if of aseptic silk, the exudate strengthening the vessel at the point of ligation. If an artery be divided and its extremity is to be secured, the knot should be sufficiently tight to prevent its slip- ping off. The ligature should be of perfectly aseptic silk, proportionate in size to the vessel to be secured, which I prefer to silkworm gut, catgut, or other animal membrane. Silk can be thoroughly sterilized by boiling, and is much safer and more reliable. The instruments necessary are a scalpel, two pairs of dissect! ng-for- ceps, wound-hooks, retractors, rat-toothed forceps, pressure-forceps, aneurism-needles, ligatures, and aseptic absorbent cotton to use for sponging; a head-mirror will be found useful for illuminating a deep incision. In securing the deeper-seated arteries, as the iliacs, broad metal spatulse and large rectangular retractors will be of use. The position of the patient will vary a little according to the artery to be secured. In general, the surgeon should stand on the side to be operated on, making the incision from above downward on the right and from below upward on the left side. The line of the artery must be well located, which may vary from what is usually given as the anatomical line of the vessel, and a special position of the part is essential, varying with the portion of the artery and the vessel to be secured ; also, the operator should be well aware of possible anomalies of position, congenital or the result of previous wounds and operations. The scalpel should be held in what is known as the dinner-knife position, and a clean, free incision made through the integument over the of the vessel, the knife entering at right angles to the surface, retaining this position when withdrawn, so that the wound should be of equal depth throughout. The length of the incision will depend entirely on the vessel to be secured, but had better be several lines too long than one line too short, so that free access to the vessel can be had. The skin should be steadied with the fingers of the left hand while it is divided. The superficial fascia, having been divided, brings us to the deej) fascia, beneath which the underlying muscles and tendons are more or less distinct. The separation between two muscles has usually to be followed, and in ordinary fleshy cases will be indicated by a white or yellowish line, but this is not so apparent in emaciated persons. The deep fascia having been divided with the finger-nail or the handle of the scalpel—its cutting edge should not be used here—we endeavor to work down between the muscles until the artery is reached, the pul- sations generally being a sufficient guide to the educated finger. If the limb was extended when the first incisions were made, it may now be slightly flexed, so as to relax the muscles and afford easier access to the artery. With retractors in the hands of an intelligent assistant, firmly held, and careful sponging of the wound with aseptic gauze or cotton, all bleeding branches either having been secured by ligature, torsion, or temporarily by catch-forceps, the sheath of the vessel is brought into LIGATION OF ARTERIES. 135 view. Superficial veins that may be made apparent by pressure and nerve-trunks or branches must be carefully avoided or pushed to one side. The artery when reached will be apparent to the sense of touch. When held between the finger and thumb it can be compressed and its pulsations will be apparent; it is less easily compressed than a vein, which swells out below on pressure, and scarcely feels like a tube, while the nerve cannot be flattened by pressure, and is firm, resisting, round, and cord-like. If an aneurism exists beyond the site of operation, pul- sation in it will cease on compressing the artery. It next remains to open the sheath and clear a part of the vessel for the passage of the aneurism-needle. The sheath is picked up with a pair of rat-toothed forceps, grasping it in a transverse position or at right angles to the course of the vessel, held firmly and well up from the artery, and a clean incision from one-quarter to one-half an inch made in it parallel with the direction of the artery; the blade of the scalpel should be inclined obliquely, with the flat of the knife toward the artery. Retaining hold on the sheath by means of the forceps in the left hand, the scalpel is exchanged for the aneurism-needle, which should be gently insinuated halfway around the artery within the sheath, enter- ing on the side of the incision held by the forceps, which are now detached, and the sheath on the other side of the incision is grasped and held up; moving the point of the needle slightly from side to side, it is gently insinuated entirely around the vessel until the eye emerges from the opening in the sheath. The ligature is then inserted in the eye of the needle, which is withdrawn, bringing the ligature with it. Care must be taken not to include a vein in the ligature, and more especially the trunk of a nerve, which can be ascertained by making careful trac- tion on both ends, slightly lifting the artery. The needle should be kept throughout at right angles to the artery, and should never be threaded until it has passed around the vessel. The ligature should be passed and tied also at right angles to the artery with a “ reef-knot,” unless there are special indications for the use of the “ surgeon’s knot.” The points of the two fore fingers, with the ends of the ligature in the hand passing over them, should meet upon the artery as the knot is being tightened, and care should be taken that the artery is not dragged out of its place. The knot should be tied gently, slowly, and firmly, avoiding anything like a jerk. The wound is closed by superficial and deep sutures if the latter are considered necessary, well dusted with iodoform, and the limb bandaged. If the main artery of a limb is ligated, it shoqjd be slightly elevated, kept sufficiently warm by artificial heat, bottles of hot water, etc. if necessary, and absolute rest maintained for two or three weeks longer— in case of the subclavian, iliac, or common femoral absolute rest is imperative for at least three weeks. Ligature of the Innominate Artery.—The patient lies upon the back close to the edge of the table, chest raised, and head extended and turned to the left, with the arm pulled down and securely fixed. The surgeon stands on the right side and in front of the shoulder. A good light is 136 SURGICAL DISEASES AND INJURIES OF TIIE HEART. essential, and means should be at hand for getting it well down into the depths of the wound. Along the upper border of the inner third of the clavicle the first incision is made about three inches in length, which is joined by one of the same length along the anterior edge of the sterno-mastoid muscle, the two joining at an acute angle. The skin and superficial fascia having been divided, the flap is dissected up. The sterno-hyoid and sterno- thyroid muscles, with a few fibres of the sterno-mastoid, are separated from the sternum, care being taken of the anterior jugular vein as it passes behind the last-named muscle at its origin, which may have to be divided ; if so, it should be secured by two small ligatures and divided between them. The deep cervical fascia is now exposed and divided in the line of the external wound, and the common carotid artery sought for, its sheath opened as low down as possible, and this artery followed until its junction with the subclavian is reached. According to Jacobson, the engorgement of the venous circulation, increased by the anaesthetic, will cause the internal jugular and the innominate veins to protrude through the wound. The artery may be flattened out by an aneurism, making it difficult of recognition ; and the cellular tissue around the vessel and between it and the sternum may be so matted with adhesions as to make it difficult to define the artery and its important surroundings—viz. the par vagum, pleura, and innominate vein. The artery must be cleared with the utmost caution, especially on the outer side; the par vagum and innominate vein may be drawn to the outside. The aneurism-needle should be passed from without in, and a little from below upward, so as to avoid the pleura as much as pos- sible. Several aneurism-needles with different curves should be at hand, and a laryngeal mirror will be a valuable aid. Ligature of the Common Carotid below the Omo-hyoid Muscle. —The patient is placed as in the former operation, the head turned slightly to the opposite side, and the hand of the affected side placed behind the back. An incision is made about three inches in length over the course of the artery, commencing a little below the cricoid cartilage and extending to just above the sterno-clavicular articulation, following the inner border of the sterno-mastoid muscle, which is exposed and drawn outward; the sterno-hyoid and sterno-thyroid are drawn to the inner side ; the omo-hyoid, if brought into view, is pushed upward. The communicating vein from the facial to the anterior jugular and the latter vein must be avoided,and the inferior thyroid veins may give some trouble. Retractors are needed and a good light is essential. The sheath is opened on the inner side, and care must be taken to avoid the descendens noni nerve. The needle is passed from within outward. On the left side the internal jugular vein may complicate the operation. Ligature above the Omo-hyoid Muscle.—Position of the patient same as in the preceding operation. Incision, about three inches in length, with its centre level with the cricoid cartilage, is made over the course of the artery. The skin and platysma having been cut through (together with branches of the superior cervical nerve), the deep fascia along the anterior border of the sterno-mastoid is cut through. The edge of this muscle having been made out, it must be followed down until the omo-hyoid is reached. The communicating vein from the LIGATION OF ARTERIES. 137 facial and the anterior jugular must be avoided. The sterno-mastoid may be drawn a little outward and the omo-hyoid downward, and the angle between the two muscles well cleared. The pulsations of the artery should now be sought, and the vessel can be readily detected as it crosses the “ carotid tubercle.” The carotid tubercle is the anterior projection of the transverse process of the sixth cervical vertebra, and Fig. 53. Surgical anatomy of the neck; ligation of the carotid, lingual, and facial arteries (Bernard and Huette). is about two inches above the clavicle. The sterno-mastoid artery and the superior and middle thyroid veins must be avoided, and care taken of the descendens noni nerve. The needle is passed from without inward. Ligature of the External Carotid.—Position of the patient same as in the preceding operations. An incision from near the angle of the 138 SURGICAL DISEASES AND INJURIES OF THE HEART. jaw, along the line of the artery, is made, terminating about even with the middle of the thyroid cartilage. The greater cornu of the hyoid bone will be about the centre of the incision. The integument and pla- tysma having been divided and superficial veins secured, the fascia is next divided, and the anterior border of the sterno-mastoid exposed at the lower part of the incision, which must be drawn outward. The pos- terior belly of the digastric is next cleared at the upper angle of the wound, and the hypoglossal nerve below it exposed, being careful not to injure it. With the finger the great cornu of the hyoid must now be sought, and the artery will be found and can be readily exposed opposite its tip, and can be ligated between the superior thyroid and lingual arteries, or below the latter if necessary. The facial and superior thyroid veins must be avoided, and lymphatic glands may lie in front of the artery. The artery having been cleared, the needle is passed from within out- ward, taking care not to include the superior laryngeal nerve, which passes down behind the artery. If it is desired to ligate above the digastric muscle, or the operation “ behind the ramus of the jaw,” the method is thus given by Jacobson : The head and shoulders being duly raised and supported, the surgeon makes an incision downward from the tragus of the ear just behind the ramus of the jaw, dividing skin and fascia. The sterno-mastoid must now be drawn outward and the digastric and stylo-hyoid downward; and it will probably be needful to divide these muscles partially in order to secure the artery before it enters the parotid gland, which must be drawn upward and forward. The needle may be passed from either side. “ This operation,” says Jacobson, “ has the disadvantage of probably entailing division of important branches of the facial nerve.” Wyeth says: “ The common carotid should never be tied for a lesion of the external carotid or its branches when there is room between the lesion and the division of the common carotid to permit the ligature of the external vessel ” (Figs. 53 and 54). Ligature of the superior thyroid artery is in all essential particulars similar to that of the external carotid below the digastric muscle, the needle being passed from above downward, care being taken to avoid the superior laryngeal nerve. The plexus formed by the thyroid veins may give trouble. Ligature of the Lingual Artery at its First Part.—Position of patient same as in operation on the common carotid; incision similar, though shorter, with its centre opposite the body of the hyoid bone. The external carotid is sought for, and carefully followed until the lingual is reached. The wound will be deep, and the first portion of the vessel more or less obscured by numerous veins (Pigs. 53 and 54). Ligature at the point of election or beneath the hyo-glossus muscle is thus described by Treves: “ The patient lies close to the edge of the table, with the shoulders raised and the face turned to the opposite side, with the arm of the affected side placed behind the back. An assistant must keep the chin well drawn upward and the lower jaw fixed. The surgeon stands on the side to be operated on. The chief assistant is placed opposite to him, and leans over the patient’s body. A second assistant stands by the surgeon’s side. His chief duty is to hold the hook which commands the digastric tendon. Full anaesthesia and the skin of the submaxillary region in the male shaved. An incision some 139 LIGATION OF ARTERIES. two inches in length, curved and with the convexity downward, is made between the lower jaw and hyoid bone, commencing a little below and to the outer side of the symphysis, and ending a little below and to the inner side of the point where the facial artery crosses the lower margin of the maxilla. Its centre is just above the greater cornu of the hyoid bone. On the right side the incision is made from behind forward, and on the opposite side from before backward. The integument, platysma, and superficial fascia are divided in the line of the incision. Certain superficial veins will be encountered, and some will probably liave to be secured. These are the submental or other tributary veins of the facial, or some tributary of the anterior jugular. It will now be convenient to resort to retractors in order that the depths of the wound may be well laid open. The next step is to expose the sub- maxillary gland, lodged in a special compartment of the cervical fascia, which shonld be opened transversely over the lower part of the gland, the organ cleared and brought well out into the wound by means of the finger and the handle of the scalpel. The gland should be turned upward on to the margin of the jaw, and kept well out of the field by a broad and well-curved retractor held by the chief assistant. The fascia exposed by lifting out the salivary gland is now to be divided transversely, and in the anterior angle of the wound the posterior edge of the mylo-hyoid muscle must be sought for and defined. The digastric tendon and the two bellies of the muscle are now to be brought clearly into view. Around the tendon, which is nearest to the hyoid bone, a small blunt hook, with a very long shaft or handle, is to be passed and held by the assistant who stands at the surgeon’s side. The tendon should be drawn downward and toward the surface. The hyo-glossus muscle can now be easily made out, and its exposed surface freed of connective tissue. The hypo-glossal nerve must be sought for as it crosses the muscle, and the surgeon’s work limited to the segment of muscle below the nerve. Crossing the hyo-glossus below the nerve, and parallel with it, is the ranine vein. This vein will about corre- spond in position with the artery, which lies beneath the muscle. I he vein and nerve should be displaced upward. The hyo-glossus muscle is divided transversely, to the extent of half an inch, a little above the margin of the hyoid bone and parallel with it. The incision in the muscular tissue must be cautiously deepened. If the cut has been we placed, the artery will bend out into th§ wound and make itself evident as soon as the whole thickness of the muscle has been divided. The needle, unthreaded, is most conveniently passed from above downward In the ligature the minute vense comites winch attend the artery are no doubt included.” , , .. . ... • •!„_ Ligature of the facial artery may be placed by an incision sum a to that exposing the external carotid or the first part of tJiepllj^a '• is more conveniently secured as it crosses the margin o ‘ j A horizontal incision is made over the course of the arteiv, along i just under the inferior margin of the jaw, one inch m length, find the artery crossing the bone at the anterior border of the nageter muscle.

Ligature of the temporal artery is applied by an incision, one inch long vertically, over the course of the artery, between the tragus and condyle of the lower jaw. It is only covered by skin and dense fascia, a single large vein lying behind and overlapping it. Temporo-facial branches of the facial nerve cross the artery, which lies behind the auriculo-temporal nerve. The ligature should be passed from behind forward. Ligature of the occipital artery may be applied close to its origin and also back of the mastoid process. In the first position an incision similar to that exposing the external carotid at its upper part will suffice. In the second position an incision nearly horizontal, two inches long, is made, commencing at the tip of the mastoid process and carried back- ward and a little upward. The skin and fascia having been divided, the posterior fibres of the sterno-mastoid are cut; next the splenius is divided, and so much of the trachelo-mastoid as many be necessary. The artery is then felt and exposed in the interval between the mastoid pro- cess and the transverse process of the atlas, which can be felt with the finger. The needle can be passed either from above or below. Ligature of the Internal Carotid.—Position of the patient and ope- rator same as in operation on the external carotid at its lower point, and the incision is also almost similar, being a little more to the outside. The anterior edge of the sterno-mastoid is exposed and drawn outward. The external carotid is found and followed down to its junction with the internal, and drawn gently inward with a blunt hook. The digas- tric muscle is drawn upward. The sheath of the vessels is opened with care, and the needle passed from without inward, observing the same care as in ligating the common trunk. The internal jugular vein, the par vagum, the sympathetic ganglion, and the ascending pharyngeal artery, all lying close to the artery at this point, must be avoided. The internal differs from the external in giving off no branches in this part of its course (Figs. 53 and 54). Ligature of the Vertebral Artery.—Position of the patient same as in ligation of the external carotid. An incision commencing at the clavicle is carried up along the outer edge of the sterno-mastoid muscle for three inches, dividing the skin and superficial fascia; a few fibres of the attachment of the sterno-mastoid must be severed close to the clavicle. The dee]) fascia having been severed, the sterno-mastoid muscle and anterior jugular veins are drawn inward. The scalenus anticus muscle is next found, and the interval between it and the longus colli muscle entered with the finger, the position of the common carotid and internal jugular vein made out, and the transverse processes of the sixth and seventh cervical vertebrae located; below that of the former the artery should be felt. The various structures must be pushed to one or the other side. The vertebral vein lies in front. Care must be taken not to damage the inferior vessels, the pleura, or the thoracic duct on the left side. The needle is passed from without inward. Ligature of the Inferior Thyroid Artery.—An incision three inches in length along the inner edge of the sterno-mastoid muscle, as in liga- tion of the common carotid, low down, the wound reaching down to the clavicle. The sterno-mastoid is drawn outward, and the carotid artery and its vein are also drawn gently outward. The transverse LIGATION OF ARTERIES. 141 process of the sixth cervical vertebra is now carefully sought, a little below which the artery may be found, passing inward behind the carotid, close to which vessel the ligature is applied, thus avoiding the recurrent laryngeal nerve. Ligature of the Subclavian Artery.—While the ligature has been applied to the first and second portions of the subclavian, it is now Fig. 55. Surgical anatomy and ligation of the axillary and subclavian arteries (Bernard and Huette), almost exclusively limited to the third part, which comprises that seg- ment of the vessel crossing the posterior triangle of the neck and where it is most superficial. The base of this triangle is formed by the outer edge of the scalenus anticus muscle and the sides by the omo-hyoid muscle and the clavicle, the latter muscle being about one inch above the bone (Figs. 55 and 56). 142 SURGICAL DISEASES AND INJURIES OE THE HEART. The artery here is covered by skin and the platysma, the cervical fascia, and a fibrous expansion extending from the omo-hyoid muscle to the clavicle, and rests upon the first rib, with the scalenus muscle behind and cords of the brachial plexus of nerves above, that one derived from the eighth cervical and first dorsal nerve being nearest the artery. The subclavian vein is below and anterior to the artery, passing in front of the scalenus anticus. The external jugular vein is usually in front of the artery, though its position may vary: the transverse cervical and suprascapsular veins, entering it here, may form a plexus over the artery. The suprascapular artery lies behind, covered with the clavicle, and the transverse cervical artery crosses beneath the omo-hyoid muscle at some distance above the main vessel. Normally, there is no branch given oil* from the subclavian at this part. In ligating the subclavian in the third part of its course the patient lies on the back, near the edge of the table, with thorax raised and head extended and turned to the opposite side, the arm pulled well down, passed behind the back, and securely fixed. The operator stands in front of the shoulder, a good light being essential. Drawing the skin over the posterior triangle well down with the left hand, an incision is made through it, reaching the clavicle. The incision, parallel with the clavicle, should be about three inches in length, and when the downward traction of the skin is withdrawn should be about one inch above the clavicle, extending across the base of the posterior triangle from the trapezius to the sterno-mastoid, with the centre of the wound even with a point about one inch to the inner side of the centre of the clavicle. The integument, the platysma, and supraclavicular nerves, with, possibly, a vein passing over the clavicle connecting the cephalic vein with the internal jugular, are divided by the incision. The amount of the trapezius and sterno-mastoid exposed will depend upon the extent to which they are attached to the clavicle (Figs. 55 and 56). The deep cervical fascia is next divided the extent of the primary incision, carefully and without the aid of a grooved director. If the external jugular vein cannot be drawn to one side with a blunt hook, it should be divided between two ligatures and all bleeding vessels secured. The outer margin of the scalenus anticus should next be made elear, and the position of the omo-hyoid developed, and if at all in the way it must be drawn upward. The finger should be passed along the edge of the scalene muscle until the tubercle of the first rib is reached, when it will be in contact with the artery and its pulsations felt, the vessel rest- ing on the rib. A little careful dissection will clear the artery and bring into view the lowest cord of the brachial plexus, which should be systematically exposed by a slight but careful dissection. The sub- clavian vein will be seen and felt, but it does not encroach upon the field of operation. The needle may now be carefully passed from above downward and from behind forward, its course guided by the fore finger of the left hand, protecting and holding the vein out of the way. In some cases portions of the trapezius and sterno-mastoid may have to be cut. The transverse cervical or suprascapular arteries may be in LIGATION OF ARTERIES. 143 the way, and must be drawn aside, and in no instance cut, as they per- form an important part in the collateral circulation. If the patient is stout with short neck, the difficulties will be en- hanced. A plexiform arrangement of the veins, their engorgement, matting together and oedematous condition of the tissues greatly increase Fig. 57. Fig. 58. Surgical anatomy of the axilla and ligation of the axillary artery (Bernard and Huette). the difficulties. The pleura must be carefully avoided in passing the needle, as well as the lower cord of the brachial plexus. Ligature of the axillary artery is practically limited to its third part. The course of the artery will be covered by a line from the cen- tre of the clavicle to the humerus, close to the border of the coraco- 144 SURGICAL DISEASES AND INJURIES OF THE HEART. brachialis muscle, when the arm is so abducted as to be at right angles to the body (Figs. 55-58). The patient is placed upon the back, close to the edge of the table, with the shoulders raised, the arm at right angles to the body and held horizontally, the surgeon placing himself between the arm and the thorax. The axilla having been shaved, an incision about three inches in length is made along the course of the artery, commencing at the middle of the outlet of the axilla, at the junction of the anterior and middle thirds, and continued downward along the inner margin of the coraco- brachialis muscle. The knife should be held with the blade horizontal, and the coraeo-brachialis thoroughly exposed after skin and fascia have been divided. This muscle, with the musculo-cutaneous nerve, is gently drawn outward, when the position of the artery may be deter- mined with the finger. In clearing the artery the median nerve is exposed, and should be drawn outward with a blunt hook, and the inter- nal cutaneous nerve pushed to the inner side. The venae comites having been well demonstrated, the needle is passed from within outward. Ligature of the Brachial Artery at the Middle of the Arm.—The limb should be extended and abducted, with the band supine and held away from the body, the arm itself unsupported, but the limb held securely by an assistant grasping the forearm. The surgeon stands on the outside of the limb on the right side and between the body and the limb on the left, making his incision from above downward. The incision, about two and a half inches in length, should be made along the inner edge of the biceps muscle in the line of the artery. The fascia, which is here thin, is exposed and divided, and, the muscular layer reached, the inner edge of the biceps clearly exposed and defined. The muscle is displaced slightly outward, and the pulsation of the ves- sel sought. If the median nerve is not brought into view, a little dis- section will clear it: in the middle of the arm it usually lies in front of the artery, and should be displaced gently to the outside: below the middle of the arm it is more conveniently displaced inward. AVhile the artery is being exposed the elbow may be slightly and moderately flexed (Figs. 59 and 60). The sheath of the vessel having been opened, the venae comites sepa- rated as well as possible, the inner one usually being the larger, the needle is passed from the median nerve. In the upper part of its course the inner margin of the coraco-bra- chialis is exposed instead of the biceps, and the ulnar nerve will be found lying to the inner side of the vessel. Ligature of the Brachial Artery at the Bend of the Elbow.—The limb, extended and abducted, may be allowed to rest on the olecranon. It should never be over-extended. An incision, two inches in length, with its middle in the centre of the “fold of the elbow,” is made through the skin along the inner edge of the biceps and parallel with its margin. The upper end of the incision will be on a level with the tip of the internal condyle, and will extend obliquely downward and to- ward the centre of the arm (Figs. 59 and 60). If the veins are normally placed, the incision will lie to the outer side of the median basilic and nearly parallel with it. As soon as the vein is exposed it should be drawn inward, and the bicipital fascia LIGATION OF ARTERIES. 145 divided in the line of the original incision. Its fibres will be found extending obliquely downward and inward. The artery, with its venae comites, being now exposed, the veins are separated and the needle passed from within outward. The vessel here is quite movable and free from attachments. The median nerve is not exposed, and is nearest the artery (on its inner side) at the upper part of the wound. Ligature of the radial artery may be applied at the upper, middle, Fig. 59. Fig. 60. Surgical anatomy and ligation of the brachial artery (Bernard and Iluette), and lower third of its course. The radial continues the line of the brachial, and a line extending from the middle of the bend of the elbow to the gap between the scaphoid bone and the extensor ossis pollicis and extensor internodii pollicis will give its position reasonably definite. In the upper third of the forearm an incision two and a half inches in length is made in the line of the artery. The radial or other surface vein may be encountered. After the deep fascia is divided the interval 146 SURGICAL DISEASES ANI) INJURIES OE TIIE HEART. between the supinator longus and pronator teres is opened up, the fibres of the supinator being vertical and those of the pronator oblique. Beneath the supinator the vessel will be found unaccompanied by the nerve. The needle can be passed from either side. The limb is supin- ated, and firmly held by an assistant grasping the hand and arm. The surgeon stands on the side to be operated on (Figs. 61 and 62). In the middle third, the limb placed as above, an incision two inches in length is made along the course of the artery, any superficial veins from the median or radial being avoided. The anterior division of the musculo-cutaneous nerve lies usually in the line of the artery between the superficial and deep fascia, and must be held aside. The fibres of the superficial fascia run longitudinally, and those of the deep fascia transverse. The deep fascia, being made clear, is divided the length of the superficial incision, and the supinator longus is exposed about the point where it becomes tendinous. The ulnar border of this muscle is defined and drawn outward; the elbow being slightly flexed will allow this to be done more easily, and the vessel will be found lying upon the insertion of the pronator radii teres, with which it is connected by con- siderable connective tissue. The nerve may or may not be seen. The vente comites being separated as well as possible, the needle is passed from either side. In the lower third, with position as before, an incision one and a quarter inches long is made over the line of the artery at the point where the pulse is usually felt, parallel with and between the supinator longus and flexor carpi radialis muscles, but must not extend below the tuberosity of the scaphoid (Figs. 61 and 62). The commencement of the radial vein lies over the artery and must be avoided. The fascia, which is here quite thin, is divided in the course of the superficial incision, and the gap between the two tendons made out. The terminal part of the anterior division of the external cutane- ous nerve is over the artery and in close relation. If it is found impos- sible to separate the venae eomites sufficiently to let the needle pass, they may be included in the ligature. Ligature of the Ulnar Artery.—This vessel, larger than the radial, follows a curved course in the upper third of the limb, and perfectly straight the remaining two-thirds. It lies too deeply for ligature in the upper third, except for arrest of hemorrhage when cut or divided, and the operation of election is left for the middle and lower third. It may be ligated, however, close to the origin of the brachial, if needed, by slightly extending downward the incision for ligating this vessel at the end of the elbow (Figs. 61 and 62). The artery in the lower two-thirds of its course will be found beneath a line drawn from the tip of the internal condyle of the humerus to the radial side of the pisiform bone. In applying a ligature in the middle third the position is the same as in ligation of the radial. An incision two and a half to three inches in length, according to the size of the limb, is made over the line of the artery. Branches of the anterior division of the internal cutaneous nerve and the ulnar vein are apt to be encountered. The deep fascia is thin, and is to be divided the length of, but a little to the outside of, the incision in the skin. The gap between the flexor LIGATION OF ARTERIES. 147 carpi ulnaris and the flexor sublimis digitorum is now to be made out by the sense of touch communicated to the fore finger. As soon as the intermuscular space is detected the wrist should be slightly flexed to relax the muscles, and with broad retractors the flexor carpi ulnaris is drawn inward and the flexor sublimis digitorum slightly outward, and the intermuscular space opened up, at the bottom of which will probably Fig. 61. Fig. 62. Surgical anatomy and ligation of the radial and ulnar vessels (Bernard and Huette) be found the ulnar nerve, to the outer side of which is the artery. The fascia binding the vessels is slight, and the venae comites are readily separated. The needle should be passed from within outward to avoid the nerve. The interspace between the two muscles is not exactly ver- tical with the limb in position for the operation, the flexor carpi ulnaris slightly overlapping the flexor sublimis, and the interspace is to be 148 SURGICAL DISEASES AND INJURIES OF THE HEART. followed down in a direction slanting toward the outer side of the ulna. In very muscular subjects the incision must be made sufficiently long. In the lower third, the arm being in the same position, a ligature is applied by means of an incision two inches long over the line of the artery, just to the radial side of the tendon of the flexor carpi ulnar is, terminating an inch or less above the pisiform bone. Care must be taken to avoid tributaries of the ulnar vein which may overlie the artery. The deep fascia, here quite slender, is exposed and divided, and the tendon of the flexor carpi ulnaris made out and drawn gently inward by a blunt hook, the wrist being slightly flexed. The vessel will now be found bound down to the flexor profundus by a distinct layer of fascia, which must be carefully divided. The nerve is close to the artery on its inner side. It may be necessary to include the venae comites in the ligature, which is passed from within outward. The palmer cutaneous nerve lies upon the artery in this location and must be avoided. The tendon of the flexor carpi ulnaris has muscular fibres entering it on the radial side down to the wrist—on the ulnar side it is quite clear (Figs. 61 and 62). Ligation of the palmar arch and branches of it and the radial or ulnar arteries is only required for traumatisms, the nature of which will determine the method of application. Ligation of the Abdominal Aorta.—The eleven cases of ligation of the abdominal aorta having all terminated fatally, it is, in my opinion, an unjustifiable operation, affording neither hope to the patient nor fclat to the surgeon; consequently it is only mentioned to be condemned. Ligation of the common iliac artery can be performed by an ante- rior or lateral incision or by the intraperitoneal method : the latter is con- sidered by Treves as the best, though it has not yet been satisfactorily tested. It can be carried out by the intraperitoneal method of reaching the internal iliac, to be subsequently considered. In the anterior incision the bowels should be thoroughly evacuated, any gaseous distention relieved if possible, and the pubes well shaved. The patient lies on the back, with thighs well extended and close together, with the head and shoulders slightly raised to relax the abdominal parietes. The surgeon stands on the side to be operated on, facing the patient, cutting from above downward on the right and in an opposite method on the left. An assistant, to whom is entrusted the care of the broad retractor to be used, stands on the opposite side. An incision five inches in length is made, commencing one and one- fourth inches to the outer side of the spine of the pubes, a little above Poupart’s ligament, the first inch and a half being made parallel with the ligament, when the incision is curved slowly upward, perpendicular to the ligament, terminating about one and a quarter inches to the out- side of the umbilicus. The three abdominal muscles and the trans- versalis fascia are divided carefully; the peritoneum is carefully and gently stripped from the iliac fossa with the fingers, pushed inward, and held out of the way with a broad retractor: the patient may be turned to the opposite side to aid in keeping the intestines out of the way. A strong needle, of good length, with lateral curve, will be found most available, which should be passed from within outward. The vein lies directly behind on the right, and to the inner side and slightly behind LIGATION OF ARTERIES. 149 on the left. Great care must be taken to avoid injury to the perito- neum. Ligature of the internal iliac artery is accomplished by the extra- or intraperitoneal method. The extraperitoneal method is identical with the anterior operation on the common iliac previously described. The peritoneum having been pushed aside until the external iliac is reached, this vessel is followed down to its junction with the internal. The wound is deep, and several varieties of needles with different curves should be at hand, and on either artery the needle should be passed from within out. By the intraperitoneal method the abdomen is opened in the median line by an incision extending from symphysis to umbilicus, or a little above in fleshy subjects. The intestines having been pushed up and drawn aside, the area of the deep wound is surrounded by aseptic gauze mats, preferable to flat sponges, and so cut off from the peritoneal cavity. The wound being held well open by broad retractors or spatulse, the peritoneum over the artery is divided to the extent of an inch and a half, and the common artery followed down to its bifurcation. The vein is much larger than the artery, and the separation will require care. The ureter must not be injured or included in the ligature, and sympa- thetic nerve-fibres must be avoided. Ligature of the Sciatic or Internal Pudic Arteries.—The patient, having been anaesthetized, is rolled over on to the face, the limb drawn over the edge of the table, and the thigh rotated in. A line drawn from the posterior iliac spine to the outer part of the tuberosity of the ischium, at the junction of its middle with its lower third, will cover the point of emergence of these arteries from the pelvis. An incision four inches in length is made obliquely across this line in the direction of the fibres of the gluteus maximus, its centre corresponding to the point above mentioned. The gluteus maximus is divided in the line of the wound, and the lower margin of the pyriformis muscle and the spine of the ischium well defined. The arteries will be found in front of the pyri- formis muscle: near its lower margin the sciatic is superficial to the pudic, and passes behind it to gain the outer side. Venae comites accompany both vessels. To the inner side of the pudic at this point lie the internal pudic nerve and its inferior hemorrhoidal branch. The sciatic here is superficial to both the great and small sciatic nerves. The ligature should be placed as near the pelvis as possible. Ligature of the Gluteal Artery.—Position as in the preceding ope- ration. With the thigh rotated in, a point at the junction of the upper with the middle third of a line drawn from the posterior iliac spine to the top of the great trochanter will overlie the gluteal artery as it emerges from the sciatic notch. An incision five inches in length, with the centre over the above-mentioned point, is made along this line. The incision runs parallel with the fibres of the gluteus maximus, which are separated the thickness of the muscle. A muscular branch may be met with which will serve as a guide to the trunk. The deep fascia between the glutei is divided, and the contiguous borders of the gluteus medius and pyriformis cleared, and the two muscles separated and held apart with retractors. The superficial division of the artery passes between these two muscles, and is followed down to the main trunk. Care must 150 SURGICAL DISEASES ANI) INJURIES OF THE HEART. be taken to avoid the vein and nerve, and the ligature should be placed as far within the notch as possible, almost within the pelvis, as the artery divides soon after emerging therefrom. Some fibres of the great sacro- sciatic ligament may have to be divided. Ligature of the External Iliac Artery.—The modified form of Sir Fig. 63. Fig. 64. Fig. 65. Surgical anatomy and ligation of the femoral, external iliac, and epigastric arteries (Bernard and Huette). Astley Cooper’s operation is as follows: The patient lying on the back, head and shoulders slightly raised, an incision is made three and a half inches long above Poupart’s ligament. The incision, slightly curved, beginning one and a quarter inches outside the pubic spine, runs for two-thirds of its course about three-eighths of an inch above the ligament and parallel with it, the outer third curving slightly away from LIGATION OF ARTERIES. 151 the ligament. The skin and superficial tissues having been cut through and the divided superficial epigastric artery secured by ligature, torsion, or pressure-forceps, the white, glistening aponeurosis of the external oblique now brought into view is divided in the line of the primary incision, following very nearly the direction of its fibres. The parts being retracted, the outer border of the conjoined tendon is made out at the inner angle of the wound. The lower fibres of the internal oblique are divided close to their attachment to Poupart’s ligament as far as necessary. The transversalis muscle is attached only to the outer third of the ligament (Figs. 63—65). The transversalis fascia, being exposed, is divided transversely over the artery and as far on either side as necessary. The deep epigastric artery lying between this fascia and the peritoneum must be avoided. The external iliac artery now being made out, the subperitoneal tis- sue about the vessels should be carefully loosened, and the peritoneum pulled from the artery and vein with the utmost care and pushed upward toward the umbilicus, and held out of the way with a broad retractor. The loose subperitoneal tissue, which forms a kind of sheath for the artery, should be cautiously cleared away and the needle passed from within outward. In closing the wound the divided fibres of the internal oblique may be attached to Poupart’s ligament, and the aponeu- rosis of the external oblique united by a few catgut sutures. Abernethy’s operation is described in South’s Chelius as follows: “ An incision four inches in length, commencing one and a half inches above and to the inner side of the anterior superior iliac spine, is carried down, curving slightly, with concavity below, to within half an inch of Poupart’s ligament, a little below its centre. The muscles are divided in order, the peritoneum exposed and pushed back as in the former method, and the vessel reached. This method enables one to reach the artery higher up, but Cooper’s operation is more easily performed.” Ligation of the femoral artery is usually performed at the base of Scarpa’s triangle, at its apex, and in Hunter’s canal. With the hip a little flexed and the thigh abducted and rotated outward, a line drawn from midway between the anterior superior spine of the ilium and the sym- physis pubis to the tuberosity of the internal condyle will indicate its course. The centre of Poupart’s ligament is to the outer side of the line of the vessels. Ligation of the common femoral is best done at the base of Scarpa’s triangle. The patient lies upon the back, with the hips a little flexed, the thigh abducted and rotated outward, the knee bent, and the leg rest- ing on its external surface. The surgeon stands on the outer side of the limb, and cuts from above downward on the right, and vice versa, on the left. An assistant stands on the opposite side (Figs. 63-67). An incision two inches in length, commencing just above the centre of Poupart’s ligament, is made downward directly over the course of the artery. The fatty tissue covering the fascia lata having been reached, is divided, care being taken not to injure any of the lymphatic nodes and the superficial epigastric and superficial circumflex iliac veins. The cribriform fascia is divided in the line of the original wound, especial care being taken to avoid the superior external pubic, the superficial epigastric, or other arterial branches. The crural branch of the genito- 152 SURGICAL DISEASES ANI) INJURIES OF THE HEART. crural nerve lies on the sheath of the artery, on the outer side. The sheath being carefully opened, the needle is passed from the inner side. Ligation of the Superficial Femoral at the Apex of Scarpa’s Tri- angle.—Position same as in preceding operation. An incision over the line of the vessel, with its centre at the apex of the triangle, is made. Pres- sure, having previously been made over the saphenous vein where it joins the deep femoral, will outline the course of the superficial veins. The saphena will generally be to the inner side of the incision. The integu- Fig. 66. Fig. 67. Surgical anatomy and ligation of the femoral artery (Bernard and Huette) ment and superficial fascia having been divided, the deep fascia is divided and the inner border of the sartorius muscle is sought for, it being the guide to the artery, and is recognizable by the course of its fibres downward and inward, underneath which the sheath of the vessels will be found. The muscle, having been detached with the finger, is held outward with a retractor, exposing the sheath, the artery in front, and the vein behind, the long saphenous nerve generally, and sometimes a nerve to the vastus internus lying on the vessel. The sheath having been carefully opened, the needle is passed from within outward, caution LIGATION OF ARTERIES. 153 being used to avoid injury to the vein. If the vein is wounded by the needle, it should be closed by a small ligature and the ligature applied to the artery higher up. A needle curved laterally will be more readily passed under the vessel. Ligature of the Superficial Femoral in Hunter’s Canal.—Position same as in preceding operation. An incision three and a quarter inches long is made over the course of the vessels in the middle third of the thigh. In the subcutaneous tissue will be found the anterior division of the internal cutaneous nerve, and to its inner side the long saphenous vein, which must be drawn to the inner side. The fascia lata is now divided in the line of the primary incision, the sartorius muscle exposed, and its anterior outer edge drawn inward. The leg being now well abducted, making prominent the fibres of the adductor magnus and the lower border of the adductor longus, the site of Hunter’s canal, lying between the adductor magnus and the vastus intern us, will be well defined. Clearing away any fatty tissue that may obscure, the part of the fascia forming the roof of IIunter’s canal, with its fibres running transversely, will be made distinct. At this point, at the outer side of the wound, the nerve to the vastus interims must be looked for. Opening the canal in the line of the wound, the artery is exposed, and the needle may be passed from either side. In front and to the inner side will be found the internal saphenous nerve, which must be avoided and care taken not to injure the vein (Figs. 66 and 67). Ligature of the popliteal artery is rarely required. Bryant says r1 u I hardly know under what circumstances this artery may require the application of a ligature, except for a wound; as for rupture of the artery or for aneurism, the operation is as inapplicable as it would be unsuccessful.” The vessel may be reached in its upper part by an incision along the outer border of the semi-membranosus muscle, and in its lower by an incision between the heads of the gastrocnemius. In the upper part the vein lies to the outer, and in the lower to the inner, side of the artery. The needle should be passed from without inward above, and from within outward below. The nerve is still more superficial, and above is still farther out, lying over the artery at the back of the knee, and to the inner side beneath the gastrocnemius. Ligature of the Posterior Tibial Artery.—A line drawn from the centre of the popliteal space to a point midway between the inner malle- olus and the heel will correspond to the lower half of the artery. The upper half curves slightly inward from this line. In operations on this artery the patient lies on the back, the knee flexed, the leg lying on the outer side, the feet on the table, secured in this position by an assistant. The surgeon stands on the outer side of limb (Figs. 68 and 69). In the middle of the calf an incision, four inches in length, in the middle third of the leg is made, parallel to the inner margin of the tibia and three-quarters of an inch behind its crest. After dividing the skin care must be taken not to injure the internal saphenous vein, which should be drawn aside. The fibres of the deep fascia, all of which are transverse, are divided and the margin of the gastrocnemius brought into 1 Surgery, p. 376. 154 SURGICAL DISEASES AND INJURIES OF THE HEART. view. The soleus is next exposed and divided the length of the incision, the aponeurosis with its fleshy fibres being cut through. Here the knife should be held perpendicular to the muscle, its edge directed toward the tibia and the blade nearly horizontal. The fascia covering the vessels and the deep muscles of the leg is now exposed, and the artery can be felt lying near the outer border of the tibia. The nerve lies to the outer Fig. 68. Fig. 69. Surgical anatomy and ligation of the posterior tibia! artery (Bernard and Huette) side of the artery. The veins are very conspicuous, and may hide the vessel, and in all probability will have to be included in the ligature. The needle must be passed from the nerve. Ligature in the lower third of the leg is applied by an incision two inches in length along the line of the artery midway between the margin of the tendo Achillis and the inner edge of the tibia. The superficial and deep fascia are divided, as well as the annular ligament at its upper LIGATION OF ARTERIES. 155 part. The artery will be found lying on the flexor longus digitorum muscle, with the nerve to the outer side. The needle is passed from the nerve, and the venae comites may have to be included. Ligature behind the Malleolus.—A curved incision, two inches long, is made about one-half an inch behind and parallel with the margin of the inner malleolus, the knife being directed toward the tibia. The internal annular ligament is divided over the artery. The vessels and nerve lie in a gap between the tendons, and can be readily made out by the touch. Separating the artery from the vein, the needle is passed from within outward (Figs. 68 and 69). Ligature of the Peroneal Artery.—The patient lies upon the sound side, almost on the abdomen, with the knee slightly flexed and the leg held firmly on the table on its antero-internal surface. An incision, three and half inches long, is made parallel with and immediately behind the outer border of the fibula, the centre of the incision corre- sponding to the middle of the leg. The fascia having been divided, the soleus muscle is exposed and drawn inward. It may be necessary to sever the lower fibres of this muscle which arise from the upper third of the fibula. Drawing it aside, exposing the fibula, the fibres of the flexor longus pollicis are severed close to the fibula until the mem- branous wall of the canal enclosing the vessels is exposed. Carefully laying this open, the artery is found lying against the inner margin of the fibula. The needle may be passed from either side, including the venae comites (Figs. 70 and 71). Ligature of the Anterior Tibial Artery.—The course of this artery will be found under a line from midway between the head of the fibula and the outer tuberosity of the tibia, extending down to the centre of the ankle-joint in front. The patient lies upon the back, the limb straight upon the table, fully rotated inward, with the foot projecting beyond the table and forcibly extended. In the upper third of the leg an incision, three and a half inches long, is made along the line of the artery, its upper end about one inch below the head of the tibia. The deep fascia is divided along the same line, and the interval between the tibialis anticus and the extensor com- munis digitorum made out. The foot is now flexed to relax these mus- cles, and the space between them opened up by finger or handle of scalpel, the external border of the tibia being distinctly made clear to the touch before the artery is sought for, the extenser communis being held down by the fingers of the left hand, while an assistant holds the tibialis anticus toward the tibia with a retractor (Figs. 70 and 71). The artery will be found lying on the interosseous membrane to the outer side of the border of the tibia, covered and held down by a mode- rately dense connective tissue. A second retractor now holds back the extensor communis, and the artery is exposed. The venae comites may have to be included in the ligature. The nerve lies to the outer side of the artery, and, as it sometimes does not join the artery until the middle third of the leg is reached, may not be seen. The needle is passed from without inward. In the middle third of the leg make an incision three inches long over the line of the artery. The deep fascia, being exposed, is divided in the interval between the tibialis anticus and the extensor communis 156 SURGICAL DISEASES AND INJURIES OF THE HEART. digitorum, the latter being tendinous at this point. The foot is flexed and the muscles separated with the handle of the scalpel, keeping in the direction of the tibia. The artery will be found on the interosseous membrane, the extensor pollicis to the outer side. The nerve will be exposed before the artery is reached, as it lies in front of the vessels. The needle may be passed from either side. The venae comites may be Fig. 70. Fig. 71. Surgical anatomy and ligation of the anterior tibial and peroneal arteries (Bernard and Huette). included in the ligature, but the nerve must be carefully protected from injury (Figs. 70 and 71). Ligature in the lower third of the leg is applied by an incision two to two and a half inches in length over the line of the artery, and just to the outer side of the tendon of the tibialis anticus, identifying with certainty the tendon. The foot need not be quite so much rotated as in the preceding operation. The deep fascia, or upper band of the annular LIGATION OF ARTERIES. 157 ligament, is divided in the same line, and the tendons of the tibialis anticus and extensor pollicis exposed and defined. The artery will be found between them on the front of the tibia, imbedded in fatty con- nective tissue. The foot being slightly flexed, the tendon of the exten- sor pollicis is drawn to the outer side with a blunt hook, exposing the artery. The nerve lies to the outer side, and the needle should be passed from it. The venae comites can be readily separated (Figs. 70 and 71). Ligature of the Dorsalis Pedis Artery.—This vessel extends from the centre of the front of the ankle, midway between the malleoli, to the middle of the first interosseous space. The patient lying on the back, the heel is steadied firmly on the table. The surgeon stands on the outer side of the foot, cutting from above downward on the right, and vice versd on the left. An incision commencing at the lower border of the annular ligament, one and a half inches long, is made over the course of the artery, and will be between the tendons of the extensor pollicis and the inner tendon of the extensor communis digitorum. The dorsal fascia is divided in the same line, and the vessel will be found imbedded in the connective tissue close to the bone. The ankle should be slightly relaxed as the vessel is sought for. The needle should be passed from the outer side to avoid the nerve. CHAPTER IV. SURGICAL DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. D. Bryson Delavan, M. D Inspection and palpation of the exterior of the neck in the neighborhood of the larynx and trachea will sometimes demonstrate deviations, deformities, and the degree of mobility of these organs. Auscultation of the larynx by means of the stethoscope is sometimes useful in cases of foreign bodies, tumors, and the like. Palpation applied to the pharynx and the entrance of the larynx is occasionally valuable. No method, however, is comparable with the laryngoscope, by which the interior of the larynx and trachea can be directly demonstrated. (Edematous laryngitis is a serous, sero-purulent, or purulent infil- tration of the submucous cellular tissue of the larynx, and is, practically speaking, an acute cellulitis. The frequency of its association with erysipelas has often been observed. The oedema may be situated above, at, or under the glottic aperture. It is generally above and in the aryteno-epiglottic folds and the ventricular bands, which, with the epiglottis, may become enormously swollen and entirely occlude the larynx. The swelling is usually bilateral. Unless resolution takes place the infiltration may become sero-purulent, and later purulent, resulting in abscess. (Edema of the larynx may be inflammatory or non-inflammatory, acute or chronic. The non-inflammatory form may occur from certain non-surgical causes. Inflammatory oedema may develop from an attack of acute catarrhal laryngitis or complicate erysipelas of the pharynx. Symptoms.—The chief local symptoms are dyspnoea, aphonia, dys- phagia, with, occasionally, cough, and a sensation of marked irritation in the throat. The laryngoscope reveals intense congestion of the larynx and often of the adjacent parts, with the characteristic swelling of the arytenoids and the epiglottis. The latter may attain such size as to entirely occlude the larynx, and thus produce asphyxia. The false vocal bands are sometimes implicated. The disease may be unilateral, but is more often symmetrical. Treatment must be prompt. In early stages applications of cold in and outside of the larynx, or, if better borne, steaming inhalations (tr. benzoin, co., acid, carbolic., or tr. opii, of either, jsj-Oij). The admin- istration of a slightly purgative dose of calomel is often valuable. Vocal and physical rest. To relieve temporarily, local applications of a 4 per cent, solution of cocaine. Should oedema become severe, scarification, per- formed with the concealed laryngeal knife, aided by larvngoscopic demon- 158 INJURIES TO THE LARYNX. 159 stration of the parts, or with Buck’s scarificator. Following scarification, application of cocaine to the larynx, as suggested bv the writer, for the purpose of constricting the cedematous tissues and, if possible, emptying them. If necessary, quick tracheotomy, in which the simplest methods are permissible, for want of better, as long as the asphyxia is relieved. The value of the O’Dwyer tube in these cases has often been proved. Besides relieving the dyspnoea, its pressure upon the infiltrated parts may actually hasten the disappearance of the oedema. These cases should be watched throughout with the closest vigilance. Injuries to the Larynx. Contusion of the larynx lias sometimes been observed. Its results may be slight and limited to the rupture of a few submucous vessels, or extravasation may be extensive and dangerous. Complicating fractures or dislocations of the cartilages may cause rupture of blood-vessels, nerves, or ligaments. The symptoms are aphonia and dyspnoea, the latter sometimes severe. Laryngoscopic examination will usually reveal the nature and seat of the lesion. Treatment of moderate extravasation when seen early consists of local rest, cold, and application of astringents. Wounds of the larynx and trachea generally complicate more extensive injuries of the neck, involving division of the great vessels and speedy death. Sometimes the larynx or trachea may be wounded, the cervical vessels receding before the knife, and thus escaping injury. ( Vide Chapter V.) Inflammation or septic infection is a more frequent source of danger in the smaller wounds, and in the larger ones necrosis, inhalation of detached fragments, growth of granulations, secondary hemorrhage, tracheo-bronchitis, pleurisy, and broncho-pneumonia. Death in from eleven to fourteen days, and recovery in uncomplicated ones in from thirty to forty. Defective voice, laryngeal stenosis, and tracheal fistula sometimes result. The prognosis is serious, especially in the case of small penetrating wounds. Treatment must be prompt and energetic. Union by first intention is unusual. Provision should therefore be made for drainage. Usually hemorrhage must be checked and asphyxia pre- vented. The air-passages must be cleared of blood, partly detached frag- ments of tissue removed, a tracheal cannula inserted, the strength of the patient sustained, and the indications in special cases actively met. Tracheotomy may be required, on account of asphyxia and to relieve hemorrhage, which the asphyxia increases. If necessary the tampon-can- nula should be employed. Some recommend a preventive tracheotomy where the constant attendance of a surgeon cannot be secured, in view of the danger of displacement of the wounded parts or of sudden oedema. This, however, is not always necessary. Sometimes the intro- duction of a large catheter or other suitable cannula may give the required relief. Where the wound is near the crico-thyroid space intu- bation may sometimes be valuable. Fracture of the Larynx.—Most common in men, and is generally due to direct violence. It may be simple or compound, incomplete or complete. The thyroid is most often implicated, the cricoid next, while 160 DISEASES ANI) INJURIES OF THE RESPIRATORY ORGANS. fracture of both is unusual, and that of the arytenoids very rare. Frac- ture may be complicated with fractures and wounds of neighboring parts and with injury to the external jugular vein. The symptoms, varying in severity, are functional disturbance, expectoration of frothy blood or of bloody mucus at or shortly after the time of the accident, stridulous respiration, dyspnoea, more or less aphonia, dysphagia, and sharp pain in the larynx, increased on pressure. Inspection will reveal swelling and ecchymosis, and over the larynx itself various irregularities, with unusual flexibility, mobility, or even crepitation of the cartilages. All of the latter signs may be absent. The symptoms are sometimes slight and recovery speedy. Gener- ally, they are either severe from the first or gradually become so. Later, the danger is from abscess, necrosis of fragments, and the forma- tion of deforming cicatrices and consequent stenosis of the larynx. The prognosis is serious, and the rate of mortality very high, especially in fractures of the cricoid. Resulting cicatricial stenosis of the larynx may make the permanent wearing of a tracheal cannula necessary. Diagnosis is easy except where there is little displacement and much swelling. Treatment.—Several methods of treatment have been recom- mended : while some cases have recovered without surgical aid, trach- eotomy has generally been advised when dyspnoea threatens. In frac- tures with displacement tracheotomy may be followed by attempts at replacement of the fragments and their retention in position by means of a suitable support. Some advise a thyrotomy and the separation of the two halves of the larynx until the fragments have united in good position, or, if some have become detached so as to obstruct the larynx, to either replace or remove them. Wagner performs thyrotomy, asep- ticizes the wound, replaces or removes the fragments of cartilage, and packs the cavity of the larynx with iodoform gauze. In some cases intubation may be found useful. In fracture of the trachea, a rare condition giving a bad prognosis, the symptoms are dyspnoea, extravasation, and emphysema, with pain on pressure over the seat of the fracture. For treat- ment, complete quietude and, if dyspnoea occur, tracheotomy. Burns of the air-passag-es may be caused by the inhalation of flame or steam or by the swallowing of hot or caustic liquids. Such accidents are quickly followed by acute inflammation, and sometimes by considerable swelling. Inflammation may extend to the trachea, bronchi, and lungs. The early symptoms arc pain, dyspnoea, dysphagia, aphonia, and shock. Respiration is rapid and stridulous, the countenance pale and anxious, and there is marked restlessness. The symptoms may be mild at first, but later severe, especially after the ingestion of caustic liquids. Often oedema of the larynx and fatal dyspnoea soon supervene, or, if these are escaped, pulmonary complications quickly follow. The diagnosis may be made from the history of the case, and, when this is unobtainable, from the lesions visible in the buccal cavity. Mild cases may recover in a few days. More often death results in from one to two days from shock or dyspnoea, or later from laryngitis, FOREIGN BODIES IN THE AIII-PASSA GES. 161 bronchitis, and pneumonia. Cicatricial stenosis of the larynx often results. Treatment.—The inhalation of flame or of steam is always a grave accident, complicated as it usually is by other injuries or burns, and by physical depression and severe mental shock. Absolute quiet should be secured, the strength supported, the digestion regulated, and the patient carefully watched for the development of serious respiratory symptoms. Many have recommended the administration of calomel. Warm inhala- tions, containing a small proportion of opium (tr. opii 3j, boiling water Oj), are sometimes successful in relieving irritation and quieting glottic spasm and cough. When oedema is imminent, if the case is seen early, cracked ice, held in the mouth, will often subdue the inflammation and quiet the pain. The patient must not be left unwatched for a moment, and if oedema occur prompt aid must be afforded by scarification and the subsequent application of cocaine. Often urgent dyspnoea develops with startling rapidity, requiring instant relief by intubation or tracheotomy. Where caustic fluids have been swallowed neutralizing agents should of course be resorted to if the case be seen in time. Foreign Bodies in the Air-passages. Liquids accidentally drawn into the larynx or trachea are usually expelled by efforts of coughing. When there is laryngeal insensibility it is more serious. The only symptoms may be severe dyspnoea and the existence of moist tracheal rales. Death follows at once or is caused secondarily by pulmonary inflammation. Spasm of the glottis and even death may be caused by the topical application to the larynx of strong medicated solutions. The entrance of blood or pus into the air-passages may cause rapid suffocation. Pus from the pleural cavity, from an abscess of the liver or of the mediastinum, may find its way into the air-passages. Treatment.—Coughing will usually suffice to expel small quantities of fluid. In severe cases, as drowning, the patient should be held with his head and shoulders directed downward, his tongue drawn well forward, and artificial respiration resorted to. Severe glottic spasm, entrance of blood or pus, may make it necessary to do tracheotomy and remove the fluid by aspiration. Solids.—The entrance of a foreign body into the air-passages must always be regarded as one of the most serious of accidents. Introduc- tion through an external wound is unusual. The variety of bodies which may be inhaled is unlimited. Their size is necessarily restricted to the diameter of the glottic aperture. Of course upon the size, shape, nature, and seat of lodgement of the object will depend largely the degree of harm which it may inflict. Foreign bodies may simply lodge in the larynx itself, or may be detained in one of the ventricles or wedged in the rima glottidis. They may become fastened in the trachea, or descend to its bifurcation, or through one of the greater bronchi into one of the more remote bronchial tubes. The right bronchus is more apt to be the seat of lodgement than the left. 162 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. The symptoms vary somewhat with the size, shape, and position of the foreign body. They are sometimes extremely obscure. The primary symptoms are—violent spasm of the larynx, choking, cough, and dis- tress ; sometimes vomiting occurs, with relaxation of the sphincters. Blood may be coughed out immediately after the accident. The dys- pnoea may prove speedily fatal, especially when a large body suddenly occludes the larynx. The body is sometimes coughed out. Often these symptoms subside after a time, but certain signs remain, suggesting its presence. The accident may be unrecognized, because the initial dys- pnoea and cough may, in some cases, be lacking. The voice may be affected. Later symptoms are—modification of the voice, continued discomfort, quickened respiration, cough accompanied with expectoration of frothy or bloody sputum. If the foreign body is fixed, the symptoms may tend to subside; but if it be movable, a change in its position is very apt to be accompanied with fresh attacks of the urgent symptoms. The general condition of the patient may not suffer, but, on the other hand, very rapid loss of strength, appetite, and weight may ensue. A foreign body in the trachea may cause severe reflex cough, together with certain changes in the current of inspired air heard upon ausculta- tion. Lodged in one of the bronchi, unless relieved it will almost cer- tainly cause death. Following the exclusion of the air, pneumonia may readily develop, or, if the foreign body be particularly irritating in its character, abscess or gangrene of the lung may be established. In such a case the diagnosis will often be a matter of extreme difficulty unless a clear history of the inhalation of the body be obtainable. Auscultation will sometimes reveal, at a certain point in the neighborhood of one of the larger bronchial tubes, such changes in the air-currents as will indi- cate partial occlusion. The prognosis, always exceedingly grave, is more serious in the child than in the adult. Caustic substances or foreign bodies, such as beans, which are capable of swelling, are especially dangerous. The long-continued presence of a foreign body in the air-passages may sim- ulate phthisis. Diagnosis.—The diagnosis, when difficult, depends upon the sudden- ness of attack, the absence of fever, and the fact that the patient is comparatively well between the attacks of dyspnoea or spasm. Some- times the patient is conscious of the movements of the body in the trachea. The presence of a foreign body in the oesophagus, causing urgent dyspnoea, may generally be demonstrated by means of the oesophageal sound. When the foreign body has entered a bronchus the passage of air into the lung of that side is, to a greater or less extent, prevented. There will, therefore, be a lack of inflation and of respira- tory murmur in that lung, without corresponding dulness or other symp- tom of acute pulmonary disease. Laryngoscopy, aided by local anaesthesia, will often be of great assist- ance in demonstrating the position of the foreign body. Treatment is often extremely difficult. The statistics of operation, although not satisfactory, are slightly in favor of surgical interference. In simple cases it is not good practice to excite cough, sneezing, or vomiting. Even the inverted position, assisted by percussion upon the back, is not recommended, although often effective with children choked PERICHONDRITIS OF THE LARYNX. 163 from the ingestion of too large morsels of food, the danger being the causing of spasm of the glottis by the impact of the body upon the vocal bands. If the foreign body is impacted in the larynx, it may be removed through the natural passages, in the case of large objects, by means of the linger or a pharyngeal forceps. Smaller bodies should be removed, with the aid of the laryngoscope, by means of suitable endo- laryngeal instruments, the parts having first been thoroughly cocainized. If the object is too large to be removed at once, it may be crushed and taken away piecemeal. If it has fallen into the trachea, one of the special O’Dwyer tubes may be inserted, in the hope that the object may be expelled through it. If it has become impacted in the larynx in such a way that it cannot be extracted otherwise, thyrotomy may be indicated, or, if the object is small, cricothyrotomy. When the body has entered the trachea, tracheotomy is required. The trachea should be opened low down, and, unless the body is easily reached and expelled, several rings should be divided and the edges of the wound widely separated, the patient inverted, and efforts made, by palpating the chest or by exciting cough, to cause its expulsion. If necessary, long, slender forceps may be used for dislodging it. Sometimes the foreign body will remain in situ for several days. Perichondritis of the Larynx Perichondritis of the larynx is an inflammation of the perichondrium and of the cartilages, sometimes followed by caries or necrosis of the latter. It is generally secondary, and rarely primary. Among its most common causes are tubercular, specific, and cancerous ulceration of the larynx. It may also follow typhoid fever, variola, scarlet fever, erysipelas, and pyaemia. It is sometimes occasioned by injury. When the perichondritis is due to deep ulceration, necrosis of the cartilage is apt to follow through impairment of its nutrition. Separation of the fragment sooner or later takes place. In some cases the destructive process is rapid and the seques- trum is quickly detached. Deformities, often leading to stenosis of the larynx, and sometimes to fistulous openings of it, and ankyloses, particularly of the crico-aryte- noid articulations, are some of its results. The symptoms are often obscure and not characteristic. Generally the pain will be increased by external manipulation of the larynx, and dysphagia and dysphonia may be present. Laryngoscopic examination, aided by the use of the laryngeal probe, may demonstrate the existence of exposed cartilage, and fragments of the latter may be expectorated or may hang more or less loosely in the laryngeal cavity. The results of direct examination may differ somewhat in accordance with the seat of the affection. At the affected point an abscess may develop. Diagnosis is made by exclusion and laryngoscopic examination. External palpation and inspection are often useful, while the fact that the concurrent disease may be attended with this complication will afford aid. The prognosis will depend upon the cause. Suppurative perichon- dritis with necrosis is often very serious, because of immediate accidents and ultimate laryngeal stenosis. In tubercular and malignant disease the prognosis is bad. In syphilis, however, the prompt and energetic use of iodide of potassium, given in frequent doses, is most effective. The iodide may be best administered in milk thickened with pepsin, in the proportion of ten grains of iodide, one drachm of essence of pepsin, 164 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. and four ounces of milk. This, made into junket, is palatable, nutritious, and easily swallowed. Where the symptoms are acute use active meas- ures, such as application of cold compresses, sucking of ice, scarification of oedematous tissues, and the prompt opening of abscesses. In evacu- ating the latter the incision should be made quickly, and the patient placed so as to enable him to rapidly expel the discharged pus. For urgent dyspnoea perform tracheotomy or insert an O’Dwyer tube. The effect of the iodide of potassium will generally render this unnecessary. These patients should be watched for a long time, and any tendency to deformity of the larynx, if possible, counteracted. Stricture of the Larynx, other than that due to inflammatory thickening and to new growths, con- sists of permanent deformity, the result of previous disease or injury, and caused either by displacement of the parts or, as is most commonly the case, by the presence of deforming cicatrices. Fractures, perichon- dritis, chondritis, ankylosis of the arytenoid articulations and “ web of the larynx,” may occasion it, but it is generally due to injury or ulcera- tion of the soft tissues which line the larynx, commonly from tertiary syphilis, and also to other diseases causing deforming cicatrices, and to destruction of the soft parts due to burns. Stenosis of the trachea may occur at various parts of this canal from the formation of bands of fibrous tissue which distort the tracheal rings. Sometimes the stric- tures are multiple. Between them are occasionally seen dilatations of the tube. The symptoms may be divided into three stages—that of active dis- ease, that of stenosis, and, finally, that of suffocation. Again, they may at first be mild and progressive, beginning with slight laryngeal stridor. This increases, being especially marked on inspiration, and is later accompanied by dyspnoea, and often bv change in the quality of the voice, which becomes hoarse in stenosis of the larynx or simply weak in stenosis of the trachea. Later, dyspnoea increases. Respiration is feeble and slow. The attacks of urgent dyspnoea are apt to take place at night, and are due to spasm of the glottis. Death may be caused by sudden asphyxia or by pulmonary congestion, pneumonia, and oedema. Sudden death from syncope will sometimes occur, due to an inhibitory action upon the bulbar centres. In stenosis of the trachea the point of greatest constriction may sometimes be determined by auscultation, as well as by laryngoscopic examination. In diagnosing this condition the existence, position, and character of the stricture must be established. It has been said that if hoarseness has preceded dyspnoea the stenosis is in the larynx ; if dyspnoea pre- ceded, it is tracheal. A mediastinal tumor, possibly compressing the trachea or bronchi, may be revealed by examination of the chest; tumor of the neck may be recognized by palpation of this region, and a laryngoscopic examination will establish the differ- ential diagnosis between paralyses, tumors of the larynx, and actual stenosis. The prognosis is serious, especially in stenosis of the lower part of the trachea, which is almost necessarily fatal. The treatment consists especially in dilatation of the stenosed TRACHEOTOMY. 165 parts. Should this fail, the permanent use of a tracheal cannula is always possible. For the actual relief of the stenosis the application of intubation has accomplished much. This may be greatly assisted by the careful and judicious division of constricting bands of cicatricial tissue before the tube is introduced. In the case of a congenital web of the larynx the simple wearing of the tube or, if necessary, removal of the web before the introduction of the tube, has given brilliant results. The patient should be examined at short intervals, the tube occasionally removed, and, if necessary, a larger one inserted in its place. This treatment should be continued until the necessary enlargement of the interior of the larynx is secured. Failing in other means, thyrotomy and excision of the offending cicatrices. Fistula of the Larynx and Trachea. The distinguishing sign of this condition is the passage of air through the external opening, together with mucus, and sometimes of pus and broken-down tissues. Inspiration is generally normal unless there is stenosis of the larynx, but the voice is often modified by the escape of the expired air, and in some cases phonation is impossible unless attempted when the opening is artificially closed. The external orifice of the fistula may be readily detected. Its internal opening may sometimes be demonstrated by the aid of the laryngoscope. These cases are not serious, although sometimes difficult to cure. The treatment consists of closing of the fistula, any existing con- dition of stenosis of the larynx or trachea first having been removed. Small fistulse may be closed by the application of mild caustics or of the galvano-cautery, larger ones by vivifying the edges and uniting them with sutures. As a rule, however, some plastic operation, such as Berger’s or Abbe’s, will be required to thoroughly close the opening. Tracheotomy is a general name for several operations employed for the admission of air to the trachea where the latter, or the approaches to it, have become obstructed. These operations are crico-thyroid laryngotomy, made through the crico-thyroid membrane; laryngo- tracheotomy, through the cricoid cartilage and the first ring of the trachea; and the two operations most commonly resorted to, high and low tracheotomy, respectively above and below the isthmus of the thyroid. Before attempting any of these operations it is imperatively neces- sary that the anatomical relations of the trachea in connection with them should be thoroughly well understood. Tracheotomy is easier performed high in the neck than low, for the anterior jugular veins are smaller above and transverse branches are rare; the muscles are somewhat separated above, while below they are in contact; the great vessels and the inferior thyroid veins are avoided. Here, too, the trachea is nearer the surface and more readily held in position. The lower the incision in the trachea, the greater the Tracheotomy. 166 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. danger of sepsis and of broncho-pneumonia. On the other hand, par- ticularly in the adult, the necessities of the case will sometimes demand a low operation. Fig. 72. Fig. 73. Trousseau’s tracheal dilator. Silver tracheotomy-tube. The Tube.—The tube should be selected with careful reference to the case in hand. The one now in common use goes under the name of Trousseau. The thickness of the tissues covering the trachea varies greatly in different individuals. Durham has therefore devised a can- nula the length of which from the neck-plate can be regulated by means of a screw-collar. The cannula itself is straight until within a short distance of its distal end. Certain defects of the Durham cannula have been avoided in the tube devised by Keen. Konig’s tube, designed for the relief of stenosis occurring low down in the trachea, is about four and a half inches long. Abbe suggests an improvised cannula for deep tracheal obstruction, made by inserting a piece of soft-rubber tubing into the trachea and transfixing its proximal end with a safety-pin. Many different devices have been made for the performance of rapid tracheotomy. They are practically never used. Tracheal tubes are composed of silver, aluminum, hard rubber, soft rubber, and celluloid. As a rule, metal tubes are preferred. The bard rubber-cannula, how- ever, is very useful when the tube is to be worn but for short time, and is more comfortable, for several reasons, than metal. The indication for tracheotomy is the presence of an occlusion of the normal opening of the larynx from acute or chronic causes, which causes dyspnoea sufficient to endanger life, which cannot be overcome by other means. The operation in itself is usually not dangerous, nor is it likely to cause serious complications to the disease for which it is employed. Its early performance where indicated, there- fore, should, wherever possible, be advised. When practicable, chloroform anaesthesia should be employed before this ope- ration. Ether causes nausea, vomiting, and embarrassing reflex movements of the larynx. The hypodermic injection of cocaine, although recommended by some, in the experience of the writer has not always succeeded in allaying the pain. In tracheotomizing children, especially in diphtheria, chloroform is apt to be contraindicated. Its administration may cause rapid increase of dyspncea, and greatly complicate an operation which under the condi- tions of cyanosis present is not likely to create suffering. The operation of tracheotomy is generally performed as follows, under chloroform unless contraindicated by dyspnoea and laryngeal irritation, TRACHEOTOMY. 167 and with proper antiseptic precautions : The patient is placed upon his back near the right side of the operating-table. A suitable firm sup- port is placed under the neck and shoulders, and the head allowed to bend backward in extreme extension. In this position the anterior Fig. 74. Position of patient for tracheotomy. structures of the neck are rendered tense, the trachea steadied, drawn as far upward as possible, and brought somewhat nearer to the surface of the neck, and the superficial veins somewhat emptied. To the assist- ant who administers the anaesthetic is also given the duty of holding the patient’s head steady and of keeping the chin exactly in the median line. The latter is very important to the surgeon, the accuracy of whose incisions is likely to be determined by the careful observance of it. At least one other assistant is desirable to attend to the bleeding and super- intend the instruments and the tube. Before making the first incision the operator should clearly define the position of the thyroid and cricoid cartilages and of the median line. With a sharp scalpel, held between the thumb and finger, an incision should be made through the integument from an inch to an inch and a half long, and precisely in the median line, downward from the level of the upper border of the cricoid, the parts on each side of the cut being steadied meanwhile by the thumb and fingers of the left hand. The movements of the thorax in respiration make it impossible to support the right hand upon the chest during the performance of the operation. Next, in the same way as above, the subcutaneous fat and the anterior cervical fascia are divided. By successive incisions, aided by the director and the handle of the scalpel, the sterno-hyoid and the sterno-thyroid muscles are reached, and the space between them opened, and the fascia covering the trachea demonstrated. Then, keeping strictly in the median line, the deep fascia is divided and the trachea laid bare. For the divis- ion of the fascia the help of a director is valuable. Any veins encoun- tered at this point in the operation should be pushed aside with the handle of the scalpel. The isthmus of the thyroid must be similarly pushed downward, and, if necessary, held out of the way with a small blunt retractor. The tracheal rings may now be felt with the finger, the fact that the trachea is actually laid bare assured, the exact situation of the cricoid noted, and the precise position of the intended opening into 168 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. the trachea located. A silk suture passed through the trachea on either side the opening, and then through the skin, tied, and the ends left long, makes a most serviceable retractor and guide should the tube require replacing. For the next division of the operation the following should be in readiness and at hand—namely: A sharp scalpel or tenotomy knife, the tenaculum, the tracheal dilator, a damp towel, and, finally, the tube, properly oiled, to which a tape of length sufficient to twice surround the neck of the patient should have been passed into one of the eyelets at the side of the neck-guard. Everything being in order and if possible all bleeding controlled, a small sharp tenaculum is passed into the cricoid cartilage in the middle line and held by the assistant, who stands behind the patient’s head. His duty is to keep the tenaculum in the median line, and with it to draw the cricoid forward and keep the trachea steady and tense. The up-and-down movement of the larynx in respiration will make it necessary to not hold the hook too rigidly. Having decided which rings to divide, the operator introduces the scalpel into the wound, the edge of the knife being directed upward, and, guided by the left fore fiuger, inserts the knife, exactly in the median line, into the lowest of the two or three selected rings (usually the first three of the trachea) and cuts directly upward toward the tenaculum. The latter is still held in position, and the knife not removed from the tracheal incision, but turned slightly upon its vertical axis, so as to separate the sides of the opening and admit the tracheal dilator, which is next inserted, and the opening sufficiently dilated to enable the tracheal tube to be passed. This should be done as easily and expeditiously as possible, and the tube at once secured in position by passing one end of the tape around the patient’s neck, through the unoccupied eyelet of the neck-plate of the tube, and back around the neck, to be tied to its fellow. The presence of the tenaculum in the cricoid excites such urgent reflexes of the larynx that until the trachea is opened the patient in many instances cannot breathe. The effect of the sudden entrance of the air is to excite such expulsive efforts of cough that the mucus, blood, or membrane which may be in the trachea are projected forth with great violence. For the protection of the operator as the trachea is being dilated, an assistant should hold a damp towel a short distance above the wound. In no case should the tube be introduced without previous separation of the edges of the tracheal incision. Disregard of this rule will defeat the attempt at introduction, and may result in serious injury to the parts, particularly where the rings of the trachea have become partly ossified. Pressure against the incision only forces its edges the more firmly together, while undue force may either frac- ture the cartilages or, from the slipping of the tube, force it downward through the tissues on the side of the trachea, thus inflicting damage. In such cases, where the tube must be worn habitually, it is better not to rely upon a simple vertical incision of the trachea, but to actually exsect a circular portion of the anterior wall equal in size to the diameter of the required cannula. The result is more comfortable to the patient, and enables the cannula to be inserted more easily. When the tube is in place the tenaculum may be removed, and the wound below the tube brought together by one, two, or three sutures. A piece of lint properly shaped to cover and protect the wound is smeared with some antiseptic ointment and placed under the shield of the cannula. Subhyoid pharyngotomy lias, oil rare occasions, been employed in LARYNGOTOMY. 169 the removal of a foreign body or of a new growth situated in the upper opening of the larynx, and particularly in the neighborhood of, or in connection with, the epiglottis. It is seldom used, since the access to the larynx accorded by it is very small. In operating, a transverse incision is made through the thyro-hyoid membrane near the inferior border of the hyoid bone and parallel with it. By means of this incision the epiglottis is exposed, and, where possible, drawn through the wound. In patients in whom the neck is thick this is not easy. The growth is then removed, bleeding checked, and the wound closed. There are no important vessels in the way, and prompt healing should result. The statistics of the operation are not good, as danger from sepsis is considerable. Infrathyroid laryngotomy has been performed for the removal of subglottic growths. In operating, the laryngotomy should be made sev- eral days before the attempted extirpation of the growths, in order to accustom the parts to the presence of the tube and thus reduce the irri- tation for the chief operation. In performing the latter the crico- thyroid space is well opened up and the cartilages separated as widely as possible. Space is then given for the removal of the growth, which should be effected by the aid of proper laryngeal instruments and methods, the cavity being sufficiently illuminated meanwhile to admit of thorough and accurate work. In readjusting the parts it is safer to allow a cannula to remain until the danger of obstructive inflammation of the larynx shall have subsided. Laryngotomy. Laryngotomy, performed by opening the larynx through the crico- thyroid membrane, is sometimes employed in place of tracheotomy. The operation is not as difficult as the latter, and may be performed more rapidly. It is not applicable to children, on account of the small size of tiie crico-thyroid space. While it may answer for emergencies, it is not desirable where the tube must be worn for any length of time. The only important vessels to be encountered are the crico-thyroid arteries, which cross this space and are usually of small size. They may, however, be large enough to give rise to serious hemorrhage. The after-management should be conducted with scrupulous care. For the first few days at least the patient should be under the supervision of an attendant thoroughly competent to provide the special assistance necessary in such cases. The tapes must be kept in order, and the tube frequently cleansed of secretion by withdrawing the inner cannula and cleaning it. The latter should be returned as •quickly as possible. It should be thoroughly disinfected and well oiled upon its inner as well as upon its outer surface before being again introduced. In the matter of feeding assistance will sometimes be gained by the use of the oesophageal tube, especially in children. The operation of thyrotomy consists in the complete division of the thyroid cartilage in the median line. It is employed in gaining access to the larynx for the removal of new growths or for other obstructive conditions, such as impacted foreign bodies, irremediable cicatricial bands, or the like. As it is likely to cause impairment of the voice, it should not be undertaken unless clearly indicated through failure of endolaryngeal methods to attain the desired end. On the other hand, 170 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. in certain serious conditions it affords the best possible opportunity for the thorough accomplishment of the purpose for which it is performed, and in good hands has been attended with excellent results. A preliminary laryngotomy or tracheotomy is required, and should be performed a number of days before the main operation. The selec- tion of the point at which the tube is to be inserted should depend upon the situation of the growth and the probable length of time that the tube will have to be worn. Should extensive bleeding be expected, a tampon- cannula must be used. In performing the thvrotomy the incision already made is prolonged upward from the median line and the tissues divided down to the cartilage, the cut extending upward to some point in the thyro-hyoid space. In dividing the thyroid cartilage it is customary to carry a perfectly true incision accurately in the median line, the crico- thyroid membranes being also divided as far as is necessary. The division of the cartilage should be effected from above downward and from without inward, and may be accomplished by means of a small but strong knife in patients in whom the thyroid has not begun to calcify. In case the latter condition is present, brilliant results have been gained by the electric saw, as recommended by Wagner. A strong scissors may also be used for the purpose. The dissection having been accomplished, the wings of the thyroid are drawn apart by means of two small sharp retractors or by means of threads passed through them, and the interior of the larynx is thus exposed. In closing the wound the two halves of the thyroid are united by two or three sutures of fine silver wire and the superficial wound closed. The subsequent treatment, in the main, will be such as is carried out after tracheotomy, special indications being met and the interior of the larynx meanwhile not being neglected. When thyrotomy has been performed for the removal of a new growth, however, and considerable injury done to the soft part of the interior of the larynx, much better results will be obtained by keeping the edges of the thyroid apart until the healing of the deeper structures shall have been completed. Some of the best operators remove the tube at once after the completion of the operation, and allow the patient to breathe through the thyroid opening. In the removal of a malignant new growth the necessity for the thorough illumination of the larynx will be apparent. For this purpose a forehead reflector should be pro- vided, and, if possible, a small Edison incandescent lamp of two or three candle-power. The application of cocaine to that part of the larynx which is occupied by the growth will render it easier to distin- guish the diseased areas and lessen the amount of bleeding. In the after-treatment the larynx is kept open, the surface of the wound dusted two or three times a day with iodoform powder or iodoform and boracic acid, equal parts; the patient’s head kept low, and the external wound covered with iodoform gauze. The patient may be able to swallow liquid food at an early date by keeping the head low during the attempt. Thyrotomy as employed for the removal of malignant disease of the larynx was formerly singularly unsuccessful. In late years, however, the results obtained by it have been increasingly better, and at the present time it promises to rank as one of our most valuable aids in such con- ditions. INTUBATION OF THE LARYNX. 171 In performing operations of this class it is sometimes necessary to prevent blood from entering the trachea, which may be accomplished either by packing the latter with sponge or gauze, or by means of a device know as the tampon-cannula. This instrument is a tracheotomy- tube around the outside of which is attached a dilatable sac of India- rubber, which, being inflated when the apparatus is in position, effect- ually occludes the trachea above the opening of the tube. Excellent modifications of the original Trendelenberg cannula have been made by Roswell Park, Hahn, Gerster, and others. Intubation of the Larynx. Intubation of the larynx, as perfected and established by Dr. Joseph O’Dwyer, is a most valuable addition to the surgery of this depart- ment. Intubation Instruments.—A set of instruments for children under the age of puberty consists of six tubes, of different sizes and varying in length from one and a half to two and a half inches; an introducer, an Fig. 75. O’Dwyer’s laryngeal tube and introducer. extractor, a mouth-gag, and scale of years. Each tube is provided with a separate obturator for the purpose of attaching it to the introducer. The numbers of the scale represent years and indicate approximately the ages for which the corresponding tubes are suitable. The female larynx in children as well as in adults is smaller than in the male. In measuring the tubes the heads are of course included. Having selected the tube, a strong thread is passed through the small eyelet at its head, and the ends tied together. Braided silk is the best, and the piece should be sufficiently long to reach the stomach and still leave a portion protruding from the mouth. The obtu- rator is then screwed firmly up on the introducer to prevent the tube from rotating while being inserted, and fixed so that the long diameter of the tube when applied and ready for use is in a line with the handle of the introducing instrument. Fig. 76. Mouth-gag. 172 DISEASES AND INJURIES OE THE RESPIRATORY ORGANS. Indications for Intubation.—The indications for intubation in chil- dren are the same as for tracheotomy. There is no reason why one Fig. 77. Extractor. should be performed earlier than the other. The beginning of the suf- focative stage is the proper time to interfere. Marked cyanosis is too late a symptom to wait for, and, besides, fatal obstruction may exist in the glottis with extreme pallor of the surface. The method of intubation applies to any obstruction of the larynx not due to a foreign body. Method of Operating.—The person who holds the child should be Fig. 78. Intubation of the larynx. seated on a solid chair with a low back, and the patient placed as repre- sented in Fig. 78. Fastening the hands in front of the chest, or thick garments in the same location, render it more difficult to depress the handle of the introducer sufficiently to carry the tube over the dorsum of the tongue. INTUBA TION OF THE LARYNX. 173 The gag is then inserted well back, behind or between the teeth in the left angle of the mouth, and the jaws very carefully separated. In children who have not at least one bicuspid on the left side, the finger shonld be used instead of the gag. An assistant holds the head firmly, at the same time slightly elevating the chin. The operator stands in front of the patient, holding the introducer lightly between the thumb and fingers of the right hand, the thumb resting on the upper surface of the handle just behind the knob that serves to detach the tube, and the index finger in front of the trigger support underneath. Held in this manner, it is impossible to use undesirable force. The index finger of the left hand is carried well down in the pharynx or beginning of the oesophagus, and then brought forward in the median line, raising and fixing the epiglottis, while the tube is guided along beside it into the larynx. It' any difficulty is experienced in locating the epiglottis, it is better to search for the cavity of the larynx, into which the tip of the finger readily enters, and which cannot be mistaken for anything else. Once in this cavity, the epiglottis must be in front of the finger. The latter is then raised and pressed toward the patient’s right to leave room for the tube to pass beside it. The distal extremity of the tube should be kept in contact with the finger, and even directing it a little obliquely toward the right side of the larynx is necessary to get inside the left aryteno-epiglottic fold, especially in very young children. The handle of the introducer is held close to the patient’s chest in the beginning of the operation, and rapidly raised as soon as the lower end of the tube has passed behind the epiglottis, other- wise it will slip over the larynx into the oesophagus. When inserted the cannula is detached by pressing forward the button on the upper surface of the handle of the introducer with the thumb, and in removing the obturator the movements required for insertion are reversed. To prevent the tube from being also withdrawn, the finger must be kept in contact with its shoul- der either on the side or posteriorly, and the tube should be carried well down in the larynx before it is detached. The gag is removed as soon as the tube is in place, but the string is allowed to remain long enough to be certain that the dyspnoea is relieved and that no loose membrane exists in the lower portion of the trachea. In withdrawing the tube the child is held as in introducing it, and the extractor is guided along the side of the finger, which is brought in contact with the head of the cannula, and then pressed toward the patient’s right, in order to uncover the aperture and allow the instrument to enter in a straight line. No attempt at extraction should be made until the head of the tube is felt. Introduction of the tube must be accomplished quickly, the whole performance not occupying more than ten seconds. To place a tube in the larynx of a struggling, choking child in the brief space of time that is compatible with safety is a difficult thing to do, and should not be attempted, except in case of emergency, without previous practice on the cadaver or on the larynx of an animal removed and placed in a suitable position. The proper time for removing the tube from the larynx will depend on the age of the patient, the character of the disease, whether of slow or rapid develop- ment, and the progress of the case. In diphtheria the younger the patient, as a rule, the longer the tube will be required. In children under two years of age it is better to leave it in seven days. When the above disease has developed slowly, and has therefore run a greater part of its course before calling for operative inter- ference, the tube can be dispensed with earlier—sometimes as soon as the second or third day. If the case cannot be seen within a reasonable time, it is safer, if progressing favorably, to leave the tube in position for seven or eight days, and the exceptions are few in which it will be necessary to reinsert it after this time,. 174 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. The tube should always be removed on the recurrence of severe dyspnoea, because it is sometimes impossible to ascertain with certainty whether it be par- tially obstructed or not. The best evidence to the contrary is a good respiratory murmur or numerous rales over the lower posterior portion of the lungs. Even under these circumstances the lumen of the tube may have been encroached upon. In cases refusing nourishment after intubation it is useless to remove the tube for the purpose of feeding, unless it has been in long enough to give some reasonable hope that its further use will not be necessary, as it is difficult to convince children for some time that they can swallow any better than before. If no dyspnoea recur in half an hour after the extraction of the tube, it is safe to leave the patient, if not at too great a distance to be reached within two or three hours. Accidents and Dangers of Intubation.—The most serious of the accidents incident to this operation is apnoea from prolonged attempts in unskilful hands to introduce the tube. Ten seconds is the longest time that should be occupied in each attempt if the child be suffering from urgent dyspnoea at the time. If the finger be then removed from the mouth and the patient be given a chance to get his breath, many attempts to properly place the tube can be made without danger, although the expert seldom requires more than five seconds to complete the opera- tion, except in difficult eases. In these, if necessary, an anaesthetic may be used. If the tube have once passed on the outside of the larynx, and this is recognized before it is detached from the obturator, it is useless to try to rectify the position without first depressing the handle of the introducer, as in the beginning of the operation. The tube may be passed into one of the laryngeal ventricles and a false passage made if care be not taken to pass it in the median line. If the patient’s head be thrown too far back, the tube may also be arrested by coming in contact with the anterior wall of the larynx or trachea. Pushing down membrane before the tube is the most serious of the unavoidable accidents attending this operation. In several such cases removal of the tube has been followed by expulsion of complete casts of the trachea, although in none of these cases was the dyspnoea relieved by the ejection of the membranes, and the immediate reintroduction of the tube was necessary because the obstruction was in the glottis. Where the child is inclined to injure the string with his teeth, the difficulty may be overcome by passing the thread between two of the double teeth. When this plan cannot be adopted, a smaller tube than the one suitable for the age should be used, which seldom fails to be rejected if obstructed. In the event of sudden asphyxia the nurse should hold the child head downward, at the same time shaking it or slapping it vigorously upon the chest. Serious obstruction does not seem to result from loose membrane above the tube, but extreme tumefaction of the epiglottis and aryteno-cpiglottic folds does in rare cases give rise to dangerous constriction at this point, necessitating tracheotomy. The tube is more liable to be expelled in the act of vomiting than by coughing. The larynx may be injured in attempting to remove the tube if the extractor be passed down beside instead of into the opening. It is important, therefore, to remember that no force whatever is required to remove the tube, and that any resistance to the withdrawal of the extractor proves that it is caught in the tissues on the outside. In feeding after intubation the entrance of food into the trachea is TUMORS OF THE LARYNX AND TRACHEA. 175 almost sure to be fatal. Liquid or semi-solid food may be given through an oesophageal tube or by enema. The best method is to allow the child to swallow it while his head is depressed and a little to one side. Intubation may be employed to relieve dyspnoea or as a curative agent to effect dilatation in deformity of the interior of the larynx. In the adult it is applicable in a large variety of conditions of laryngeal stenosis, both acute and chronic, among which may be mentioned obstruction to the larynx or oedema glottidis from any cause; injury to the larynx from fracture, incised wounds, or internal violence, as from attempted endolaryngeal operation, foreign body, or the like. The chronic conditions in which it is indicated are such cases of stricture as may be amenable to treatment by the division of cicatricial bands and systematic dilatation. These include cicatricial contractions resulting from syphilis and other diseases attended with laryngeal ulceration, and from traumatisms and chronic thickening of the soft parts, in which the subglottic variety may sometimes be included. It is also useful in some cases of laryngeal neoplasm, in laryngeal paralysis threatening asphyxia, and in advanced tubercular laryngitis with obstruction. It may also be useful in fracture and other injuries of the laryngeal cartilages. The insertion of the tube is less difficult in the adult than in the child. It should be done, if possible, with the aid of the laryngoscopic mirror, although this is not absolutely necessary. In passing the tube the larynx should first be anaesthetized with cocaine. The patient should be seated as for the ordinary laryngoscopic examination, and the tube, aided by the mirror, should be introduced as in the infant, excepting that the finger of the operator is not used as a guide. Instead of this, as is customary in the passage of any endolaryngeal instrument, the aid of the patient is depended upon to open the larynx, either by the act of phonation or deep inspiration. The use of a mouth-gag in the adult is not required. Intubation in suitable chronic cases has practically superseded all older methods of dilatation. While the larynx tolerates the presence of the tube with great readiness, too long retention may injure it, and is not recommended. Such a case should of course be watched, and the tube removed and reinserted as often as required by cleanliness, the condition of the parts, or the necessity for more active dilatation through the insertion of a tube of larger diameter. Tumors of the Larynx and Trachea. New growths of the larynx may affect it primarily or may extend to it from neighboring parts. They may be either benign or malignant. Distinction between the two varieties is sometimes extremely difficult. The so-called tubercular specific tumors which are occasionally seen in the larynx are not properly to be included in this class of affections, and should be considered elsewhere. The etiology of benign growths of the larynx is practically un- known. Although more common between thirty and fifty, they may be observed at any age, and one form of growth, papilloma of the larynx, may be congenital. These tumors are more common in men than in women, and their most frequent location is upon the vocal bands. Subglottic tumors are comparatively rare. Intraglottic growths usually spring from the free border of the anterior part of the vocal bands—those above the glottis from the epiglottis and from the aryteno- epiglottic folds, the subglottic from the inferior surface of the vocal bands. The benign tumors which may occur in the larynx, somewhat in order of frequency, are—1. Papillomata; 2. Fibromata; 3. Cystic; 4. Angeiomata ; 5. Adenomata ; 6. Myxomata ; 7. Lipomata; 8. Chon- dromata. Although these growths occur in considerable variety, there are but few that are seen with any degree of frequency. 176 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. The symptoms of intralaryngeal growth will depend upon the loca- tion, the size, and the shape of the tumor, whether it is pedunculated or not, and, to some extent, upon the age and characteristics of the patient. The most commonly observed symptom is the alteration in the quality of the voice. This, at first hardly perceptible, becomes more and more marked, until finally complete aphonia may result. Especially is this the case with new growths situated upon the vocal bands. The change in position of a pedunculated growth may cause sudden and marked alteration in the symptoms, while a vascular growth, particularly in the early stages of its development, may demonstrate its presence or not in accordance with the state of activity of its circulation. Dyspnoea, gen- erally wanting in the adult unless the growth should have attained con- siderable size, in the infant is commonly present and may be urgent. It is generally more severe at night than during the day, is accompanied by stridor, and is due to obstruction by the growth, the inflammatory conditions excited by it, and sometimes by the attendant spasm of the glottis. It may be so simple as to pass unnoticed, or so severe as to cause death from asphyxia, varying with the location of the growth. Cough in the adult is usually not marked, and is distinctly laryngeal in character. In the child it is a frequent symptom, and often severe. It is spasmodic, and is sometimes accompanied with haemoptysis. There is rarely dysphagia or pain. The only satisfactory means for studying these growths is by the use of the laryngoscope. The expectoration will seldom give evidence of their existence. Their progress is usually slow, varying with the nature of the growth. Papillomata sometimes increase rapidly, especially where a growth has been irritated by attempts at removal, by intercurrent acute affections, or by over-use of the voice. Their duration is, of course, variable, and they may recur after removal, especially papilloma and cyst. The prognosis depends upon the nature of the new growth and upon the age and general condition of the patient. It is far more serious in the infant, on account of the difficulty of endolaryngeal operation, and also because in the child the papillomatous variety is the most common. Of all the varieties of growth, so-called diffuse papilloma is by far the most serious, on account of the difficulty in differentiating it from epi- thelioma. Recurrence is frequent in this, contrary to what is true in the case of other benign growths. Tr eatment.—Laryngeal growths are probably less common now than formerly, by reason of the early and effective treatment of the subacute and chronic affections of the upper air-passages, and especially those of the nose. As to the actual treatment to be pursued in a given case, everything will depend upon the age and condition of the patient, the location, size, and shape of the growth, and, most important of all, upon its histological character. The possibilities of the treatment of papilloma may be considered as follows : In infants, particularly where the growth is interfering with respiration, it should generally be removed as speedily as possible. Thyrotomy in many cases has given excellent results. MALIGNANT GROWTHS OF THE LARYNX. 177 Danger from the growth of granulations may be avoided by the wearing of a tracheal cannula. Whether a supposed papilloma is in reality a malignant growth or not, it should never be unduly irritated. If the tumor be pedunculated, circumscribed, and located conveniently, there are few objections to its removal by endolaryngeal operation. When, on the other hand, it is sessile, difficult to reach, or multiple, such attempts may give imperfect results or be followed by quick recurrence, and other methods may be indicated. Of these the one attended with the best results in the experi- ence of the writer is the frequent daily application to the interior of the larynx of a spray of strong alcohol. Under this, persistently continued, growths of considerable size have entirely disappeared. Local rest is imperative. Complete cure has more than once followed tracheotomy. In the employment of the endolaryngeal method the larynx is first cocainized, and while its interior is being demonstrated by the laryngo- Fig. 79. Dundas Grant’s laryngeal forceps. scope a suitable instrument is introduced into it, and the growth, or a fragment of it, seized and removed. Many different methods and instruments are used for this purpose. Among them may be mentioned evulsion by means of forceps (Mackenzie’s, Grant’s, Shroetter’s, Krause’s); crushing or “grattage” (Voltolini), by which such parts of the growth as are not removed are so injured that they either slough or are destroyed by the resulting inflammation ; incision with laryngeal knife or scissors; excision by means of specially constructed laryngeal instruments or by the cold-wire snare or the galvano-eaustic loop; cauterization by means of the galvano-cautery or chemical caustics, such as chromic acid, nitrate of silver, and chloride of zinc. Malignant Growths of the Larynx Malignant disease of the larynx may be intrinsic or extrinsic, pri- mary or secondary. It may be sarcomatous or carcinomatous. Epithe- lioma is by far the most common. Laryngeal cancer most frequently attacks men at middle life. It may occur, however, in the young. Local irritations seem to favor its pro- duction. In its earlier stages it is generally unilateral. Sarcoma commonly originates either from the true or from the false vocal bands, although it may spring from almost any part. The tumor 178 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. is usually rounded, and single or somewhat lobulated. Tts surface may be either smooth or somewhat papillary or rugose. The color is gen- erally red ; sometimes, however, it is grayish-yellow, and in other cases of a darker color than the surrounding membrane. Often, especially when ulceration has taken place, it may be difficult to distinguish it from papilloma, and the diagnosis can only be established by microscopical examination. When the disease is making rapid progress and destroy- ing and infiltrating the structures in its neighborhood, it is difficult to dis- tinguish it from carcinoma. It is commonly of the spindle-celled variety. The favorite points of departure for epithelioma of the larynx are the ventricular bands. It may arise, however, from one of the vocal bands, the epiglottis, the aryteno-epiglottic folds, or, indeed, from any part of the larynx. As the disease extends it becomes impossible to identify the point of origin. In general, it is apt to originate from parts which are subject to a certain amount of irritation. The appearance of the growth in its first stages is variable. It may occur as a small papillary tumor, as a rounded well-defined swelling, or as a diffused infiltration. The first variety is often impossible to differentiate from true papilloma. A valuable early diagnostic sign is the general infiltration of the muscles in the neighborhood of the growth, resulting in a marked corresponding loss of motion, as also is the tendency of epithelioma to advance from the middle of the larynx backward: in papilloma the opposite is true. The microscopical demonstration of epithelioma will of course estab- lish the diagnosis. Failure to find it, however, does not by any means exclude it. In the later stages diagnosis is less difficult. The surface becomes ulcerated, covered with unhealthy granulations, and bathed in fetid pus; the surrounding mucous membrane is inflamed, and sometimes there is considerable submucous oedema. The cartilages are attacked, and sometimes those in its neighborhood become ossified, especially the upper tracheal rings in extensive epithelioma of the lower part of the larynx. Deformities of the exterior contour of the larynx appear, and as the disease progresses the neighboring parts outside the larynx be- come involved in a process of general destruction. The TREATMENT OF MALIGNANT TUMORS OF THE LARYNX may be either palliative or curative. The palliative treatment may be either therapeutic or surgical. For the former, various topical applications may be made to the affected parts by means of solutions, sprays, powders, or vapors. Solutions are generally used in the form of atomized sprays, and are employed for purposes of cleansing or disin- fection, to subdue pain, and to retard or overcome the progress of the growth: they may consist of antiseptics (Dobell’s solution, listerine, boracic acid, and the like), anodynes (cocaine or morphine), or caustic medicaments. The comfort of the patient may be enhanced and much local and general irritation prevented by keeping the parts strictly cleansed and by great care in the matter of feeding. By the surgical palliative treatment dyspnoea may be relieved by intubation or trache- otomy, and obstructing fragments of the growth may be removed. The curative treatment may be divided into three classes—namely, endolaryngeal operation, laryngo-fissure or thyrotomy, and laryngectomy or extirpation of the larynx. LAR YNGECTOMY. 179 Tumors of the trachea may be benign or malignant. The benign growths, often referred to as polyps, are generally either fibromata or papillomata. Submucous cysts, multiple enchondromata, and osteomata have been observed. In addition to these may be mentioned the various kinds of growth composed of granulation-tissue which develop after tracheotomy either during the time the cannula is in position or, as occasionally happens, in the cicatrix of the wound. The dyspnoea which they cause sometimes necessitates reopening the trachea for their removal and the reintroduction of the cannula. The treatment consists in the removal of the growths. This may occasionally be done through the natural passages, as described by Jarvis, or with the Grant forceps in cases where the growth occurs in the vicinity of the glottic aperture ; otherwise, tracheotomy and removal by suitable means. In operating, the head of the patient should be low, in order that the blood may not gravitate into the bronchi. Laryngectomy. In total excision the patient lies on the back with a pillow under the shoulders, the head being somewhat low. A preliminary tracheotomy is often performed and a tampon-cannula inserted. An incision is made in the median line from the hyoid bone to a point a little below the cricoid cartilage, and a transverse incision over the hyoid bone meets this at its upper end. On exposing the larynx the sterno-hyoid muscles are drawn to one side and severed close to their insertion. The soft parts are bluntly dissected from the larynx. Vessels are ligated as encountered. After the sides of the larynx become free the inferior constrictor of the pharynx is cut close to its insertion into the thyroid cartilage. The trachea is next cut across just below the cricoid, and drawn forward, while its lumen is well packed with sponges or iodoform gauze, after the insertion of a trachea tube of proper size and form. Where possible, preservation of the lower half of the cricoid will aid in the adaptation of the artificial larynx. The larynx is dissected from the deeper parts until the upper corners of the thyroid are freed. Finally, the thyro-hyoid membrane is cut across and the larynx removed. The epiglottis is removed or left in place according to its condition. If it is desirable to see the inside of the larynx before removing it, the thyroid can be split down the middle and the sides held apart, while the upper end of the trachea is packed with sponge or gauze. The organ can then be removed piecemeal. The partial operation is usually performed by splitting the thyroid down the middle, packing the upper end of the trachea, and then removing as much of the larynx as is desirable. After the operation the upper end of the trachea is packed firmly with gauze to prevent blood and saliva from flowing into it, and the rest of the wound stuffed lightly witli an antiseptic gauze. Foreign material may be prevented from entering the lungs by elevating the foot of the bed. Nutritive enemata are given for the first forty-eight hours; then a stomach-tube may be passed through the wound into the oesophagus and gastric feeding begun. The packing is removed from 180 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. the wound as often as necessary, and the parts washed with a weak antiseptic solution. If suited to the case, an artificial larynx may ultimately be inserted. The simplest and best of these is the one devised by Bond of London. In a modification, practised with brilliant success by Cohen, the whole larynx is removed and the free end of the trachea fastened to the outside of the cervical wound. This secures complete removal of the growth, and subjects the patient to the minimum of risk of impair- ment of special function and usefulness of the part, of discomfort, and of outward deformity. The chief danger, aside from unskilful technique and accident occurring during operation, is that of septic infection or of septic pneumonia. Injuries to the Epiglottis. In a wound of the epiglottis the question is whether the injury can be spontaneously repaired or whether the removal of the lacerated or diseased portion may be desirable. Experience has proved it advisable, where necessary, to remove almost any portion of this member, patients who have suffered its entire; loss being able to swallow, with the exercise of a little care, without difficulty. In certain conditions of disease—as, for instance, where the epiglottis has been so deformed by contraction as to obstruct the larynx, or where it is the seat of severe tubercular dis- ease—the removal of the offending portion may be undertaken. This is sufficiently easy, and may be effected by the use of the galvanic cau- tery, snare, or by properly-curved cutting forceps. New growths of the epiglottis, when situated upon its anterior face, are often easy of removal,, especially where the growth is not of a malignant character. The Uvula and Soft Palate. Malformations of the uvula include asymmetry, absence, congen- ital elongation, and the condition known as bifid or double uvula. Congenital elongation of the uvula has been observed as hereditary. This condition, as well as elongation from simple relaxation, is easily remedied by the amputation of the redundant part. Bifurcation, a result of arrested development, is quite common. To relieve the more pronounced cases the tips may be removed, and the* inner aspect of each denuded well up to the base, and then brought together. Amputation of the uvula is now practised with more discretion than formerly. The simplest and best instrument for its performance is a pair of long-handled scissors, one blade slightly hooked at its tip so that the uvula may not slip from its grasp. A holder, made on the principle of the thumb-forceps and about eight inches in length, possesses the advantages over other forceps that it has not the inconvenient scissors- handle, that it may be held firmly and with great steadiness by allowing its proximate end to rest in the hollow between the thumb and fore- finger, the whole hand meanwhile being steadied bv resting the fourth and fifth fingers against the patient’s chin, and, finally, that in applying the scissors the forceps may be used as a guide. THE UVULA AND SOFT PALATE. 181 In operating, the patient’s tongue should be held down by himself or by an assistant with a tongue-depressor, and he should be instructed to breathe quietly, so that the throat may be relaxed and the pharyngeal region kept in a quiescent state. The amount necessary to be removed having been carefully estimated, the uvula, under cocaine anaesthesia, is grasped by the forceps at a point below the proposed line of incision and held carefully in position, care being taken to avoid stretching it, the result of which is to drag the mucous membrane so far downward that in removing it the parts beneath are denuded and the healing process thereby greatly retarded. The scissors, carefully guided by the hand and eye of the ope- rator, are then applied and the separation of the redundant tissue is completed. The same result maybe obtained by means of the Jarvis snare, in the use of which it is only necessary to seize the part to be removed in the loop of the £craseur without the aid of the forceps. This latter method is not painful if cocaine anaes- thesia be employed, and it is sometimes convenient and effective. The amount of relief possible from this simple procedure is sometimes remarkable, the symptoms, local and reflex, vanishing quickly, the general health returning to a normal basis, and the voice gaining markedly in quality and power. In very rare instances hemorrhage, troublesome in its character, has resulted from this operation. New Growths.—Papillomatous growths, generally of small size, but sometimes of sufficient dimensions to cause irritation, are occasionally seen upon the uvula near its free extremity, and may be either peduncu- lated or sessile. Myxomata and angeiomata may also occur. Malignant growths of the uvula and soft palate are occasionally encountered, usually, however, as an extension of the disease from adja- cent parts. Syphilis, tuberculosis, lupus, and lepra of the velum and uvula are met with—the first often, the last three rarely. Syphilis of the Velum Palati.—The occurrence of the primary lesion of syphilis, although now and then observed upon the tonsil, is, upon the velum, almost unknown. The tertiary form of syphilis may occur in the soft palate at any period of time beyond two years after the primary infection. It is characterized by true ulceration or loss of tissue, and is the result of the degeneration of gummatous deposit. The effects upon the velum palati of tertiary syphilis are often most disastrous. Two varieties of cases may be described: 1. Those in which simple ulceration has taken place at or near the margins of the velum, without material loss of substance, so that the adhesions are limited and the greater part of the velum itself is intact. In these the progress is good. 2. When the loss of substance has been consider- able, and when the soft palate has become extensively adherent to the pharynx, relief becomes a matter of extreme difficulty, and in many cases is next to impos- sible by any known plan of treatment. Complete adhesion, although rare, is some- times seen. The results of extensive adhesion of the velum to the pharynx are most dis- tressing, and may be summed up as follows : Mouth-breathing; impairment of the quality and tone of the voice; interference with drainage from the nasal cavities and naso-pharynx; consequent upon this, loss of hearing from irritation of the Eustachian tube and the almost inevitable occurrence of serious middle-ear dis- ease ; loss of the sense of olfaction. When the passage to the lower part of the pharynx is contracted there are sometimes dysphagia and dyspnoea. The treatment of this condition consists in the attempt to separate the adherent tissues, and to establish, more or less perfectly, commu- nication between the upper and lower pharynx. In operating, by cutting against the point of a sound passed through the nose into the upper pharynx and used as a guide, an entrance may generally be effected. 182 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. By skill, ingenuity, and unremitting patience much may be done to help the sufferer. In general, however, the prognosis is very unsatisfactory. Operations must sometimes be done under anaesthesia, and the hemorrhage which not infrequently attends such attempts is sufficient to call for the use of a tampon-cannula. Secondary hemorrhage is also not uncommon. Congenital malformations of the pharynx are of rare occurrence. Of congenital malformations of the neck, the pharyngeal fistula is by far the most common. This is divided into two varieties, the complete and the incom- plete. They are, as a rule, unilateral, and occur more commonly on the right side. They are usually incomplete. Their external opening is usually found upon the side of the neck, anywhere in the course of a line from the sterno-clavicular articulation to the angle of the jaw. Rarely they may open in the median line over the larynx or trachea. The internal opening is generally found in the lateral wall of the pharynx, behind the cornu of the hyoid bone and near the tonsil, or in the pharyngo-palatine arch. The canal varies in length and in diameter, is usually somewhat tortuous, and sometimes so much so as to be almost impassable to a probe. Its diameter is always greater than that of the external opening, and it can be much increased by retained secretions. The diagnosis is from the history of the case, the position of the opening, and course of the canal as demonstrated by the probe. The existence of an inter- nal opening may sometimes be found by probing or by injection through the canal of a colored liquid. The treatment is sometimes very difficult. It depends upon the destruction of the epithelium lining the canal by caustic injections, notably those of iodine; by direct cauterization with the galvano-cautery; or by the radical extirpation of the fistula throughout its entire extent. Operation is often difficult and dangerous. Congenital Malformations of the Pharynx. Retropharyngeal Abscess. Circumscribed abscesses of the pharynx are generally due to the breaking down of lymph-nodes. Their situation in the neighborhood of the pharynx causes them to manifest peculiar symptoms and to be attended with special dangers. Three varieties may be recognized— the retro-, the lateral, and the anterior pharyngeal. Chronic abscess of the retropharynx is a common disease in the young. It is a serious condition, threatening as it does the life of the patient, but one which is, as a rule, entirely remediable by the prompt application of proper treatment. Although almost invariably found in infants, it has occasionally been observed in adult life. A debilitated condition in general, chronic cachexia, and the influence of certain infectious diseases may all pre- dispose to it. A serious form of retropharyngeal abscess is sometimes found in per- sons suffering from caries of the cervical vertebrae. The early symptoms are like those of ordinary pharyngitis. The pharyngeal inflammation, however, continues, and, instead of subsiding, the swelling continues to increase. The neighboring cervical lymph- nodes may be enlarged. The attack is sometimes sharp and well pro- nounced, and in other cases it is slower in its course • the symptoms are less conspicuous and the development of the condition is insidious, the progress of suppuration being very slow. The first variety is more common. Its onset is characterized by high fever, headache, and FOREIGN BODIES IN THE PHARYNX. 183 vomiting, sometimes by chills and convulsions. The symptoms of the acute sore throat are more or less severe, with considerable pain in swallowing. Another prominent symptom is dysphonia. Pain is especially marked in the back of the throat and is increased by move- ments of the head. The treatment of retropharyngeal abscess in its early stages is similar to that of acute inflammatory conditions of the pharynx. Upon the earliest detection of pus, free incision should be made through the posterior wall of the pharynx into the abscess, the most prominent part of the swelling or that at which the fluctuation is most distinct of course being selected. In doing this the pharynx should be clearly demon- strated, full preparation made for the operation, and the instant the knife is withdrawn the patient, if an infant, should be inverted to pre- vent the escaping pus from entering the larynx. In the adult the patient’s head may be caused to hang over the edge of a table. Anaes- thesia is contraindicated. Lateral abscess of the pharynx may closely resemble phlegmonous tonsillitis. It differs, however, from the latter disease in being caused by the suppuration of a lymph node. The symptoms are analogous to those of retropharyngeal abscess, excepting that dysphonia is less severe. Symptoms caused by irritation of the accessory or pneumogastric nerves may sometimes arise. External inspection and palpation of the neck may demonstrate the presence of a localized swelling in the neighborhood of the angle of the jaw, while an inspection of the pharynx will show a condition hard to differentiate from acute tonsillitis. This form of abscess is commonly acute, and is generally recovered from. Its proximity to the great vessels of the neck, and particularly the carotid, renders it a source of some danger to these organs. Treatment.—Incision is not always possible through the wall of the pharynx, and in many cases it will prove easier to reach it from the outside. External incision has been highly recommended, because it is the best means of thorough evacuation and treatment of the cavity. Where pus has migrated into the mus- cular planes of the neck this treatment will of course be required. Hemorrhage from one of the great blood-vessels from erosion of its walls is almost necessarily fatal. Nevertheless, in such a case the common carotid has been successfully tied. Foreign Bodies in the Pharynx. Small objects are apt to be lodged in the tonsil or entangled in the adenoid tissue at the base of the tongue. Larger substances will be more commonly found either in the glosso-epiglottic or the pyriform sinuses. The sensations and opinions of the patient as to the existence of a foreign body in the pharynx are unreliable, hypersesthesia of the pharynx often simulating the latter condition. Examination should be conducted by the aid of a strong light and cocaine anaesthesia. Irritability may be relieved by the swallowing of ice or very cold water. For direct inspection of the throat it is sometimes useful to assist the action of the tongue-depressor by pressing upward the thyroid cartilage, thus bringing the different parts into view. Failing to discover the object in this way, the laryngeal mirror should be used. The practice of digital examination of the throat, although valuable, should be made a last resort, on account of the reflex irritation which it excites. A small object in the tonsil may easily escape detection. It is always well to sweep a probe gently over the surface of the gland, and to examine with a rhino- scopic mirror behind the palatal folds. The extraction of one object does not preclude the possibility of others remaining. 184 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. The treatment depends upon the immediate extraction of the offending subject, with means at hand for the proper demonstration of the throat and suitable curved forceps to accomplish removal. Where the body is lodged very low in the pharynx and is of a shape which renders its extraction through the natural passages impossible, entrance to the pharynx from the outside may be demanded. The continued presence of an irritating body in the throat may give rise not only to dangerous local symptoms, but to cough and local irritation of a dis- tressing character, causing the general condition of the patient to rap- idly deteriorate. Lymphoid Hypertrophy at the Vault of the Pharynx. Lymphoid hypertrophy at the vault of the pharynx is a condition of chronic enlargement of the tissue at the vault of the retronasal space, otherwise known as Luschka’s tonsil, the pharyngeal, or the third ton- sil. As commonly met with, it is of two varieties. In the first the lymphoid element may be associated with more or less fibrous tissue; in the second the latter is but feebly represented. The size of the growth may be so great as to practically fill the retronasal space, or, on the other hand, it may be so small as to make it difficult to determine whether or not its condition is path- ological. It may be confined strictly to the vault, or be diffused over the posterior and lateral walls of the pharynx, or it may exist upon the posterior wall of the pharynx alone, either in a large well-aggregated, tumor-like mass or in more or less thickly scattered elevations. Its symptoms are, first, those due to mouth-breathing—namely, a dull, stupid expression of the face, anaemia, drooping of the eyelids, open mouth, projecting teeth, arched palate, pinched nostrils, and the deformity of the chest known as “pigeon breast.” Again, there is mental dulness, loss of hearing, nasal obstruction with all the dis- tressing symptoms of which it is the cause, defective speech, and, generally, almost constant catarrh, the secretions from which are swal- lowed, with the result of producing indigestion. The occurrence of reflex effects is shown in frequent headache, irritative cough, laryngeal spasm, and other neurotic symptoms, including in some exceptional cases such extreme results as chorea and, it is said, epilepsy. Even in the infant it may be suspected through the presence of mouth-breath- ing, snoring, and a marked inability to perform the act of nursing. Fig. 80. Position of adenoid enlargement as commonly located in the upper pharynx. LYMPHOID HYPERTROPHY AT THE VA ULT OF THE PHARYNX. 185 One effect of the obstruction to nasal respiration is the permanent deformity of the bony framework of the nose and hard palate which generally accompanies it. Considering these things, it becomes important to secure the early recognition of the necessity for treatment in such cases, and to see that it is promptly and efficiently carried out. This must depend in some degree upon the nature of the growth, the size to which it has attained, and upon the age of the patient. In a few instances, where the disease is acute or subacute, where the tissue is soft, and the amount of growth small, the application of resorptives and the administration of alterative and tonic medicines, together with careful attention to hygiene, may possibly accomplish a cure. Almost invariably however, these means will be found unsatis- factory. In the surgical treatment of this condition by far the most effective method is its forcible removal by means of some surgical operation. For removal by operation many instruments have been devised. These may be divided into four classes: a, those made upon the principle of the curette; b, the double curette or forceps; c, the wire loop; and, finally, d, the adenomatome. The first class includes the ring-knife of Dr. Meyer and its modifications and the sharpened finger-nail of the operator, a useful adjunct to the more complicated instruments; the second, the forceps of Loewenberg and its varieties; the third, a modification of the Jarvis snare; and, finally, the fourth, a double cutting instrument, furnished with scissor blades, called the adenomatome. Of these instruments, the most generally useful are a modified Loewenberg forceps and the sharp curette. The other instruments necessary for operating under anaesthesia are a good mouth-gag and a soft-palate retractor. The latter should be made with a shank broad enough to protect the uvula from injury during the process of operation. The position of the patient during operation is of considerable im- portance. Two methods, performed under complete ether or chloroform anaesthesia, are in common practice: In the first, applicable mainly to infants, the child is held upon the lap of an assistant in the sitting pos- ture, with the head upright and turned toward a good light. The head is steadied by a second assistant, who also manages the mouth-gag and administers the anaesthetic. The soft palate may be drawn upward and forward by means of the palate-retractor or White’s palate-hook, or it may be secured by tapes passed inward through the nose and outward through the mouth, the ends being tied outside after Wales’ method. With the head inclined forward in this position the blood caused by the operation will tend to escape from the mouth, instead of being swallowed. Moreover, the pharynx can be well illuminated and the steps of the ope- ration better directed by the aid of vision. The position upon the back is preferred by many good operators, requiring as it does the services of but one assistant, and being the one to which a large majority of sur- geons are better accustomed. It is not so favorable as regards the admission of light to the pharynx, and therefore it requires a greater degree of skill on the part of the operator, whose tactile sense must be highly educated by way of substitute. The blood, instead of flowing from the mouth, is swallowed into the stomach. This is not a disad- vantage, for it trickles down from the posterior wall of the pharynx and escapes into the oesophagus almost without making its presence felt, unless the flow excited has been considerable. 186 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. A possible objection to the upright position is the additional risk of fragments of detached tissue falling into the larynx and thus causing asphyxia. Such accidents have been reported, having occurred in the Fig. 81. Gottstein’s curette. course of the use of the Gottstein curette. This would not be possible under the use of the forceps. The management of the palate-retractor should be entrusted to a skilled assistant, as upon this the convenience, and to some extent the success, of the operation will depend. Removal by curette or forceps is sometimes practised without anaesthesia. While it may be called for in some cases, it is apt to be exceedingly painful, and far less thorough than by the method just described. The operation is attended with more or less bleeding, generally of no import- ance, but sometimes considerable. It is best, therefore, that the tissue be torn away rather than cut. This method has the additional advantage of greater thoroughness, as masses of adenoid much larger than the fragment grasped by the instrument are frequently separated, and by this method it is not likely that the healthy and more resisting parts will be injured. Remnants left by the forceps may be removed by the finger-nail, by Hooper’s forceps, or by means of a small carefully-guided curette. Should the removal of a mass of adenoid be followed by undue bleeding, it is well to defer further attempts at operation for a few moments until the hemorrhage shall have ceased, or, at least, until it shall have sufficiently diminished. Too great force in the separation of a fragment of tissue must be avoided. It is better to release the mass included in the grasp of the for- ceps and seize a smaller portion, or else, by applying them in a somewhat different position to separate adherent fragments, than it is to attempt to accomplish too much at once. As large masses of hypertrophied tissue often exist upon the pos- terior wall of the pharynx as well as upon the vault, it is necessary to secure the removal of these with the rest. The corners of the upper pharynx also, immedi- ately above the Eustachian prominences, must be carefully cleared. In operating upon the upper pharynx general anaesthesia is of the greatest possible value both to the physician and to the patient. With it ample time is afforded for careful examination and for the checking of undue bleeding should any occur; perfect control of the operation, as well as of the patient, can be main- tained; absolute relaxation of the throat can be secured; the inducement of retching from pharyngeal irritation, that most active and persistent of reflexes, can be avoided ; troublesome remnants of the growth can be recognized and removed; undue excitement can be prevented ; and finally, the whole work can be accomplished without the knowledge on the part of the patient of what has been done. Following operation, the general condition should be made as perfect as possi- ble, change of air often being beneficial, and the patient should be carefully examined in order to determine whether or not the operation has resulted in a thorough and complete success. Should the contrary prove to be the case, further treatment may be called for, and although, when properly performed at first, it Avill seldom be necessary to repeat the operation, there is no reason why this should not be done when required. Indeed, it is well in difficult cases to mention to the parents beforehand the existence of such a possibility, especially in dealing with very young patients. Nasopharyngeal. Tumors. This variety of growth, fortunately, is of rare occurrence. It origi- 187 NASOPHARYNGEAL TUMORS. nates usually about the time of puberty, tending to subside after the patient is of age, and is most common in males. The etiology is unknown. The tumors generally arise from the basilar process of the occipital bone and the base of the body of the sphenoid, whence they may extend to almost any part of the pharynx, the nose, or its adjacent sinuses. The development of the growth is active up to the twentieth year. After this, however, it ceases to grow, and by degrees will atrophy and practically disappear. While not highly malignant in itself, it is exceedingly dangerous from the destruction to surrounding parts which attends its progress. Inspection shows that the surface of the tumor is smooth, even, and rounded, and numerous large vessels may appear upon it; its color varies from a pale pink to a deep, congested reddish color. In the nasal fossa the growth appears dark red in color, dense in structure, firmly attached, and easily made to bleed. The membrana tympani are of course depressed, owing to the interference with nasal respiration. Treatment.—While its base is still absolutely limited to the pharynx, operation through the natural passages is clearly and unmis- takably indicated. For this purpose the Scraseur, either in the form of the galvano-caustic loop or the cold snare, has been found decidedly the most practical. In the employment of the electric loop the best method is, if possible, to surround the base of the growth with the galvanic ecraseur, passed either through the nose or through the mouth. The inclusion of the growth within the loop is often difficult. Much easier manipulation is made possible by the use of a separable double cannula, through which the wire may be passed. The curved cannula, carried behind the palate, is inferior to that used through the nose. The loop, aided by the finger in the pharynx, should be fixed to the highest possible point. The above directions relating to the cold snare will apply as well to the incandescent loop, which is in some respects superior. With the latter the density of the growth may be more readily overcome, result- ing in the destruction of some of the remaining tissues, and the danger of hemorrhage almost entirely done away with. Only a moderate degree of heat should be applied. Attempts to tear the growths away piecemeal will be likely to cause serious hemorrhage, and are absolutely contraindicated. Excision without preliminary operation is, from the danger of hemor- rhage, unjustifiable. Ligation is sometimes useful. The use of the galvano-cautery, both in the form of the loop and for the destruction of remnants or of points of recurrence, makes it possible to thoroughly eradicate fibromatous growths. The electrolytic method is sometimes of great value. Great aid is afforded the surgeon in these manipulations by the inva- riable enlargement of the pharyngeal space which is present. When the growth has advanced beyond the vault of the pharynx and removal by the natural passages is impossible, the old method of removal after a preliminary operation must be discussed. While such radical procedures have now and then succeeded, the general statement may be made that they are far inferior in safety and success to early operation with the loop. Three varieties of procedure have been 188 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. employed—namely, operation carried on through the nose, through the mouth, or through an entrance effected by operations more or less for- midable upon the superior maxillary bone. Fibro-mucous Polypi.—These are composed of a mixture of the structural elements of the tissue from which they originate. They vary from a tumor of small size to one sufficient to fill the upper pharynx, and are generally smooth, dark red, and ovoid in form. They are probably more common than true fibromata. The symptoms to which they give rise are principally those of nasal obstruction. They are otherwise harmless to the surrounding structures, and are not prone to bleed. They show little tendency to recur when removed, and may be extirpated by evulsion, or, better still, bv the cold- or the hot-wire loop. Enchondroma.—Enchondroma of the nasopharynx is extremely rare. Malignant Tumors.—Malignant tumors of the nasopharynx, al- though rare, are really less uncommon than has been supposed. The symptoms are similar to those of fibromata, but to these are added in certain cases severe pain of a lancinating character, which is apt to be referred to the ear and to be worse at night, severe dysphagia, and general cachexia. Sarcomatous tumors may be pedunculated, while sometimes they are more or less distinctly lobulated. They present no special features to the eye or to the touch by which their true nature can be detected. The latter can be established by the aid of the microscope. The prognosis is absolutely bad. The progress of development is rapid, and recurrence after removal is almost certain. The best plan of treatment consists in early recognition of the growth and its removal by the galvano-cautery or by electrolysis, any sign of recurrence being attacked at once. Epithelioma.—Carcinoma of the pharynx is rare. In such cases the comfort of the patient may be enhanced and the progress of the dis- ease retarded by the repeated thorough removal of the soft, fungating masses which fill the upper pharynx. Dermoid Tumors.—These rare abnormalities are undoubtedly con- genital. Chronic Hypertrophy of the Tonsils. Chronic enlargement of the tonsils consists in an abnormal increase of the lymphoid tissue of the organ, sometimes accompanied with a pro- liferation of its fibrous stroma. The latter is apt to occur where the disease is of long standing, although not uncommon in the young. The hypertrophic process is most active at the age of puberty, after which time it tends to decline until beyond thirty the disease is more uncom- mon. It may originate, however, at almost any time before adult life. It has been present in old age. The symptoms are usually plain and easily recognized, and are in many particulars similar to those which accompany the local obstruction and irritation found with lymphoid hypertrophy at the vault of the pharynx. In some cases the tonsils are chronically inflamed, without being materially enlarged, the condition giving rise to annoying symp- CHRONIC HYPERTROPHY OF THE TONSILS. 189 toms. These cases may be much relieved by the application of astrin- gents to the crvpts, or, still better, by the opening up or cauterization of such of the latter as are either dilated or inflamed. Tonsillotomy.—Of the methods for removing the tonsil most com- monly used, may be mentioned cauterization by chemical or electrical escharotics; ecrasement, by means of the galvano-caustic loop or of the cold wire; abscission, by means of some modification of the knife or scissors. Both ligation and the injection into its substance of various supposed absorbents only need be mentioned to be condemned. The practice of enucleating the tonsil with the finger has lately been revived in some quarters. Excepting in young children it is of questionable value. During the operation the patient should sit facing a good light, the operator with his back to it. By those familiar with the use of the head-mirror the latter, however, will generally be preferred. The patient, if an adult, should sit upright and well back in the chair, the head fixed against a properly-adjusted head-rest or supported by an assistant. The latter should stand directly behind the chair, and, while holding the head with both hands, should place the fingers of each hand over the tonsillar region of the corresponding side—that is, immediately below the angle of the jaw. Thus the tonsils may be prevented from receding before the pressure of the tonsillotome when it is introduced, and the operation may be performed with greater accuracy and thor- oughness. Having engaged the tonsil in the ring of the instrument, push the blade firmly and steadily through the included tissue, separate the frag- ment of tonsil, and, withdrawing the instrument quickly, remove the excised gland adhering to it, and at once, and before the patient realizes that there is to be a second operation, before bleeding sets in, and with- out giving opportunity to cough or clear the throat, excise the remaining gland. Thus both may be removed at one sitting, so that but one con- valescence is to be endured : few young patients will submit to a repe- tition of the operation. The Physick tonsillotome has been modified, so that the handle may be reversed, enabling it to be used first in one hand and then in the other. Ambidexterity in the use of the one instrument is far better. The operation may generally be done very quickly. As a rule, anaesthetics are not indicated in tonsillotomy. Cocaine anaesthesia is often effective, although, if the child is highly sensitive, irritable, or feeble, chloro- form or nitrous oxide may be desirable. The introduction of the instrument into the pharynx is often more complained of than the actual separation of the tonsil. Bleeding after operation is usually slight, and soon ceases spontaneously; if not, it may generally be checked by simple means, such as direct application to the cut surfaces of a mixture of one part gallic and three parts tannic acid, slightly reduced with water and applied upon a pledget of cotton. The sucking of cracked ice is also effective. Sometimes, however, hemorrhage may be severe, and, while fatal results have very rarely occurred, there are several cases on record in which this accident has taken place. With regard to this question, it may be said that moderate hemorrhage requiring direct pressure or astringents to check it is not very unusual: a severe hemorrhage occasionally occurs, and in view of the enor- mous number of tonsillotomies done the proportion of serious results has been exceedingly small. The source of the bleeding may be either arterial, from the division of one or two comparatively large arterial branches, or from the division of a large number of small arterial twigs; venous, from the division of the small plexus of veins which lie outside and below the tonsil; and capillary or general, 190 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. from the presence of the hemorrhagic diathesis. The records show that hemor- rhage has very rarely occurred before the eighteenth year. This may be explained by the presence of the larger amounts of fibrous tissue in the adult tonsil. Park has discovered a new styptic of extraordinary efficiency, easily made by mixing fairly strong (25 per cent.) watery solution of antipyrine and alcoholic solution of tannin. A most tenacious, gummy mass is thrown down, which when applied on cotton or sponge with a little pressure will check all oozing. Foreign Bodies in the Tonsil. Foreign bodies may develop spontaneously in the tonsillar crypts through retention of the secretions of the latter. The presence of such a cheesy mass may give rise to much irritation. The condition should be relieved by removal of the deposit and free opening of the crypt. In rare instances a true calculus of the tonsil has been found. The presence of a tonsillar calculus may be determined by the discharge of fragments of the calculus, by inspection, a part of the mass being visible, or by examination with the finger or probe. Their removal may be accom- plished either by enlarging the mouth of the crypt and extracting them or by excision of the tonsil. Their presence may pass unnoticed, not only by the patient, but by the physician, the symptoms often being obscure. Tumors of the Tonsils. Tumors of the tonsils requiring radical operation are usually malig- nant, and are either epitheliomatous or sarcomatous. The latter are generally of the round-celled variety. The rapidity of their growth, their tendency to recur, the readiness with which the neighboring lym- phatic nodes become infiltrated, and, finally, the important anatomical position of the tonsil, all militate against the success of efforts made to remove them. Operation may prolong life and give a certain measure of relief, however, and in some cases at least it has effected a cure. It should never be attempted without the clearest possible understanding, not only of the normal regional anatomy of the vicinity, but, in partic- ular, of the important arterial trunks near by and their possible anoma- lies. Tumors of the tonsils may be removed through the mouth or through incision in the neck and into the pharynx. The latter method is called pharyngotomy. Operation through the Mouth.—In cases where the tumor is well defined and projecting, as in the case of some sarcomata, and, now and then, of epitheliomata which have developed in an already enlarged tonsil, removal may be successfully accomplished by means of the gal- vano-caustic loop or even with the cold-wire ecraseur, and such diseased tissue as remains subsequently taken away by any suitable method which may recommend itself. Even in this operation a preliminary trache- otomy is sometimes necessary. This method is less dangerous, and its results are as good as those of the more severe operations. From the depth and obscurity of the parts a good light is indispen- sable. The writer has employed with great satisfaction a small incan- descent electric lamp, which, introduced into the deepest recesses of the pharynx, demonstrates clearly the various parts under observation, thus enabling the surgeon to distinguish between affected and healthy tissues and to locate accurately any bleeding point. Such a lamp, of from one- TUMORS AND POLYPS OF THE NASAL CAVITIES. 191 to three-candle-power, should, if possible, be provided in case its use be required. The three principal operations known as pharyngotomy for the removal, from without, of malignant tonsillar disease are Cheever’s, Czerny’s, and Mikulicz’s. Tumors and Polyps op the Nasal Cavities. The form of tumor known as simple mucous polyp, naso-fibroma, or, incorrectly perhaps, nasal myxoma, is by far the most common form of neoplasm found in this region. The etiology of these growths is obscure. Their duration is often difficult to determine. The symptoms are, in general, those of obstruction to breathing, loss of the olfactory sense, local irritation, and persistent catarrh. They are usually referred to a time at which the patient became especially susceptible to acute coryza: the symptoms have grown progressively more annoying, and they finally reach a state where they are incessant. When located comparatively high or confined to one side, the patient may be unaware of their presence. On the other hand, the growths may actually protrude from the vestibule of the nose. As nasal obstruc- tion becomes more pronounced the symptoms and the general discomfort become more severe. Mouth-breathing, snoring, and fatigue upon com- paratively slight exertion are usually present. Ileflex symptoms are not uncommon, such as headache, oftentimes severe, neuralgia in different localities and especially through the distribution of the facial nerve, reflex cough, and, finally, marked asthmatic attacks and neuras- thenia. The eye may suffer from irritation of the conjunctiva and lachrymation and from various more or less obscure disturbances of vision. The auditory apparatus may also be seriously affected, owing to the obstructed nasal respiration, the catarrhal inflammation, and the possible reflex irritations which the polyps may excite. Vertigo, impair- ment of memory, mental hebetude, and insomnia are more or less com- monly observed. The symptoms of coryza may vary from a tendency to sneezing and to the appearance of a watery discharge, apparently from slight exposure to cold, to catarrhal symptoms of the most pro- nounced and inveterate character and with excessive secretion. Pro- nunciation is affected, and the tone-quality and carrying power of the voice greatly impaired. The peculiar inability to fix the attention in these cases is called aprosexia. The treatment of nasal polyps should be first, thorough removal, and, second, prevention of recurrence. For the former various means have been employed from an early period, some of which are still in use. External applications to the growth are generally ineffective. Rarely, astringents may retard development and add to the comfort of the patient. The means most commonly employed, however, are those by which the growth is removed with forceps, separated by means of a wire snare, or destroyed by the galvanic cautery or ring knife. In order to operate intelligently and successfully the nasal cavity, under cocaine anaesthesia, should first be demonstrated by anterior rhinoscopy, the removal of as many polyps as possible effected, and, when sufficient 192 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. hemorrhage has occurred to obscure the parts, further operation deferred until another sitting. Variously constructed forceps are used for this operation, and for the removal of certain varieties there is no better method. In general, alligator forceps, the jaws of which should be serrated and not too large, will be found the most convenient. The most generally useful and least painful instrument for the removal of polyps is the Jarvis snare. For the removal of small growths situated Fig. 82. Jarvis snare. high in the nasal cavity a finer quality of piano wire than that com- monly employed is desirable. The removal of cystic growths is often difficult from their great size. Incision into the wall of the tumor will, if it be a cyst, cause it to col- lapse, when it can be removed with ease. The galvano-caustic loop for the removal of simple nasal polyp is seldom necessary. A fine ring knife is sometimes useful for the removal of growths which are hard to reach by other means. Little immediate treatment is needed after operation beyond pro- tecting the sensitive membrane from the too free access of the air, especially in bad weather, and the keeping of the parts properly cleansed and disinfected. The necessity for aseptic instruments is emphasized by the fact that dangerous pysemic symptoms have followed the care- less removal of a simple mucous polyp. For the prevention of recurrence the growths must not only be removed, but the localities from which they have originated must be absolutely freed from all trace of their presence. Either at the time of removal or subsequently applications of the galvano-cautery or other caustic should be made for this purpose. The nasal cavities should be treated locally meanwhile with alkaline and antiseptic sprays and, if necessary, with astringent solutions. Removal of the anterior extremity of the middle turbinated for access to the region which it covers may sometimes be required for the extirpation of polyps, but should be practised with great caution. In the rare event of polyp appearing in the course of an atrophic rhinitis, its presence may act as a stimulus to secretion, and thus prove helpful. Insects and Foreign Bodies in the Nose. The impaction of a foreign body in the nose is a common accident. The entrance of living organisms, on the other hand, is somewhat rare in temperate latitudes, but sufficiently common in tropical and subtropi- cal countries. While the former seldom gives rise to severe symptoms, the latter may readily prove fatal. Foreign bodies are most apt to lodge in the widest part of the canal. Any object sufficiently small and capable of locomotion, such as an in- sect, may find its way into one of the adjacent sinuses. A foreign body INSECTS AND FOREIGN BODIES IN THE NOSE. 193 may give rise to great irritation, as may also attempts made to ex- tract it. The variety of foreign bodies which have been found in the nose is very great. The list comprises extraneous substances introduced either by accident or design by infants or insane adults; sequestra of diseased bone; and parasites. The history is usually as follows: A child of about two years of age unobserved thrusts some small rounded object into its nostril. Soon symptoms of unilateral chronic inflammation are established, the irrita- tion often being severe and the discharge extremely fetid. The body, if too firmly impacted to be dislodged by simply blowing the nose, remains fixed until removed by the surgeon. Not infrequently the presence of a foreign body passes unsuspected for many years, and the child is treated indefinitely for simple catarrh. Treatment.—Preparatory to removing a foreign body first cleanse the mucous membrane anterior to it. Then thoroughly anaesthetize the membrane with a 6 per cent, solution of cocaine. The passage thus hav- ing been widened, the body may often be extruded by simply blowing the nose. Should it still be so firmly impacted as to require the use of an instrument, its removal will be greatly facilitated by the anaesthesia of the parts as well as by the additional space provided. A probe or small forceps will often answer the purpose of extraction. If necessary, the body may be first crushed. The copious hemorrhage which com- monly results from the old method of extraction is not likely to follow after the use of cocaine, for the reason that less injury is done to the parts. In all cases of fetid catarrh, particularly when confined to one side and dating back to infancy, careful examination with speculum and probe should be made, the nostril having first been thoroughly cleansed by means of a warm douche and the presence of a foreign body excluded before a positive diagnosis is made. Diagnosis is generally easy. In some cases, especially of long stand- ing, the foreign body may be completely concealed by the secretions of the nose or by a mass of granulations. In the latter case the appear- ances have often been mistaken for syphilis, malignant disease, or lupus. Examination with a probe will at once determine the nature of the trouble. After removal of the object the nostril should be washed several times a day with a weak disinfectant. Cure quickly follows. The so-called rhinoliths, or nasal calculi, are concretions formed of the earthy salts of the nasal secretions. Sequestra of bone, particularly in tertiary syphilis, sometimes remain in the nasal cavity after their separation, thus acting as foreign bodies. Fungi and Parasites.—Various fungi, as well as ascarides, leeches, centi- pedes, and earwigs, have found their way into the nasal cavities. The symptoms commonly present after such an accident are epistaxis, sneezing, headache, lacliry- mation, nasal discharge, and stenosis. In the tropics, seldom elsewhere, various kinds of flies may enter the nasal chambers, preferably of a patient suffering from catarrh, and there deposit their eggs. These are quickly hatched, causing in succession irritability, tickling, and sneezing; later, formication, bloody discharges, and epistaxis, with redness of the face, eyelids, and palate; excruciating pain, generally frontal, insomnia, and, if the 194 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. condition continue unrelieved, necrosis of the parts, convulsions, coma, and death. Sometimes the larvrn are sneezed out, or they may be seen on examination of the nose, which of course will establish the diagnosis. The destruction caused by them may extend to the mucous membrane, the cartilages, and even to the bones of the head, the ethmoid, sphenoid, and palate bones having been found carious. The extension of the destructive process is often very rapid. Treatment should be prompt and efficacious, and should be selected some- what with reference to the stage of development of the larvaj and the progress which the condition has attained. If the case can be seen before the larvae have migrated too far or have buried themselves too deeply, it is possible to cause their immediate and thorough expulsion by local cleansing, cocaine anaesthesia, and the inhalation of chloroform or of ether, the effect of the last-named drugs being to cause the insects to voluntarily vacate the nose. Insufflations of calomel and injec- tions or infusions of tobacco, of turpentine, and of alcohol have been recommended. Of these, the two former seem to have given the best results. As failure to obtain relief is fatal, the propriety of surgical operation in extreme cases is worthy of consideration. Rhinoscleroma. This rare condition involves both the integument and the mucous membrane of the nose, whence it extends indefinitely. The disease appears in the form of well-defined tubercles, rounded prominences, or flat structures of considerable density, which begin upon the alae and adjacent parts of the lips. The tubercles may be of the color of the skin or else of a brownish red, shiny upon the surface, devoid of hair, and traversed by dilated blood-vessels. Rigidity of the affected parts becomes apparent in consequence of the infiltration. Pathologically, the growth seems to resemble round-celled sarcoma, although differing from it by the presence of certain small hyaline bodies of highly refracting power which seem to form its characteristic element. The latest investigations seem to demonstrate that certain microbes are an evident factor in its propagation. The fact that it is infectious has been proved by successful inoculation of the cultures of these micro- organisms. ( Vide p. 217, as well as Vol. I. p. 76.) The disease must be differentiated from syphilis by the failure of con- stitutional treatment; from epithelioma by the appearance of the ulcer- ation ; from keloid in that microscopically the latter is composed entirely of fibrous tissue. The only known treatment is excision. Epistaxis. Epistaxis, or hemorrhage from the nasal cavities proper and their accessory sinuses, may be either active or passive. It may occur from violence, from some remote pathological condition, or as a vicarious phe- nomenon. The former is the most common. The bleeding may come from one nostril alone or from both. It may originate in the deeper part of one nasal cavity, and, owing to some stoppage on that side, be deflected into the nasal cavity of the opposite side, and emerge through that nos- tril or into the pharynx. Hemorrhage occurring during sleep, and the patient in such a position that the blood gravitates into the pharynx, might easily escape detection until serious loss of blood had resulted. Changing the position of the patient and causing him to clear his throat would probably demonstrate the presence of the bleeding. EPISTAXIS. 195 Treatment.—Before attempting to treat epistaxis it is necessary to determine, as far as possible, its precise origin and cause. Vicarious hemorrhages and those occurring at the critical period of certain fevers may be allowed to continue unless excessive. With the plethoric also, and especially where it appears instead of menstruation, it should not be hastily interfered with. To stop the flow simple means will gener- ally prove effective, such as absolute rest, the supine position, avoidance of allowing the head to hang forward, and standing with the head erect and the arms raised above it. The application of cold to the nose and the insufflation of cold water are effective, while the injection of water as warm as can be borne is an excellent styptic. Whenever possible direct applications should be made to the bleeding point, the latter hav- ing been carefully dried, with absorbent cotton, of nitrate of silver, of chromic acid, or of the galvanic cautery. Various astringents, such as alum and tannin, may also be used directly upon the bleeding point. The injection of a solution of antipyrine, from ten to twenty grains to the ounce, has been found effective. If necessary, control of the hemorrhage may be gained by plugging the parts in the neighborhood of the bleeding. Anteriorly, this may easily be accomplished by pack- ing against the bleeding surface a tampon of absorbent cotton, or, still better, one composed of a narrow strip of surgical gauze upon which some styptic—as, for instance, tannin—has been sprinkled. Park has Fig. 83. Plugging the nares with Bellocq’s cannula (Fergusson). recommended most highly the combination of solutions of tannin and antipyrine (each of 10 per cent.), by whose union a most tenacious and powerfully styptic substance is formed. This may be applied directly. Occurring posteriorly, the bleeding may be checked by inserting a tam- pon in the nasopharynx, and, if necessary, at the same time packing the anterior part of the nasal canal. For this a flexible catheter or Belloeq’s cannula is used. The latter consists of a cannula curved at one end, through which is passed a curved steel spring, the end of which is protected by means of a perforated ball. In order to 196 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. use the Bellocq cannula a loop of silk should be threaded through the eye in the end of the cannula. The steel should be drawn backward into the cavity of the can- nula before the introduction of the latter into the nasal canal. To introduce the cannula pass the extremity with the silk loop through the nostril and backward along the floor of the nose to the posterior wall of the pharynx. Having reached the latter, thrust the steel spring forward, so that it shall emerge from the cannula and appear beneath the soft palate. A tampon of cotton, lint, or sponge, saturated with vaseline, should have previously been prepared and attached to the middle of a stout piece of soft woven silk, the latter about eighteen inches long. One end of this silk should now be securely tied to the loop of silk in the eyelet of the cannula, and with the aid of the latter, assisted by the finger placed in the phar- ynx, the string should be drawn forward through the nasal cavity until the tam- pon arrives in the lower pharynx. Here, by means of gentle traction made upon the string, combined with careful pressure upward from the finger, the tampon should be forced into the upper pharynx as desired. The tampon having been duly placed, it is well to make a firm block of absorbent cotton, around which the anterior nasal end of the string may be wound and held in the vestibule of the nose. The pharyngeal end of the string should be conducted out of the mouth and loosely attached to the patient’s ear. In removing the tampon there is con- siderable danger that the parts may be irritated and thus the bleeding again pro- voked. It should never be drawn forcibly from the pharynx. The best plan, as a rule, is to first cleanse the parts as thoroughly as possible, and then apply a weak solution of cocaine in order to cause as much contraction of them as possible. While it may be considered in some cases necessary to do so, it is not desirable to allow the tampon to remain in the pharynx for more than twenty-four hours. Severe bleeding may require the use of revulsives intended to cause reflex con- traction of the nasal blood-vessels, the administration of remedies intended to quiet the action of the heart, the application of pressure internally as well as ex- ternally, and, in extreme cases, transfusion or some kindred measure. The Accessory Sinuses. The sinuses adjacent to the nasal cavities, and communicating with them, are four in number—namely, the frontal/ the ethmoidal, the maxillary or antrum of Highmore, and the sphenoidal. It may be said of them all that they are located in regions of great anatomical importance, that the diseases to which they are sub- ject are of an unusually serious character, and that the treatment which the latter may require for their relief is such as to demand the highest degree of special skill. The accessory sinuses may be the seat of hypereemic and of in fective processes. The first condition generally complicates an attack of acute rhinitis, and may be difficult to distinguish from the latter except for the localized pain which it may occasion. Suppurative disease of these parts is an affection of much greater importance, the symptoms being more severe and the resnlts more serious. The most important of the latter is the development of various abnormal conditions of the soft tissues lining the cavities, and of caries or necrosis of the bony struc- tures underlying them. These diseases may develop from simple acute catarrh, from chronic rhinitis, or, in exceptional instances, from trau- matic causes. In the maxillary sinus disease is often due to dental irritation. Local destructive processes accompanying syphilis or tuber- culosis may possibly give rise to them. The exciting cause of the trouble is usually a lack of free drainage of the sinus through its natural opening. The chief causes may be regarded as occlusion, followed by acute, and later bv chronic, suppura- tion. The inflammatory processes resulting from this extend to the periosteum, and necrosis finally supervenes. The obstruction to the canal may be either in its continuity or at its mouth, in the latter case THE ACCESSORY SINUSES. 197 caused by thickening of the soft tissues surrounding it or deformity of the adjacent bony parts. The symptoms of sinus disease are often obscure, and diagnosis difficult. When pain is present, it may be of two kinds: the first is deep-seated, dull, and throbbing, and located in the neighborhood of the affected sinus. In addition to this, neuralgic pains of the most intense character may appear, sometimes distinctly radiating from the affected centre and sometimes difficult to trace. In the more chronic cases pain may be more or less wanting. External swelling over the frontal and maxillary sinuses may be present in extreme cases. The location of the pus exuded into the nasal cavity, although apt to be misleading, is sometimes a guide as to its source, that issuing from the ethmoidal cells or the maxillary sinus pouring downward from beneath the middle or the anterior border, respectively, of the middle turbinated body. By the method of transillumination pus may be demonstrated in unilateral disease of the maxillary and frontal sinuses, although this test is not always to be relied upon. The principles of the treatment of these diseases may be summed up under three heads—namely, free drainage, systematic cleansing of the cavities, and removal from them of diseased tissues and bone. The special application of these principles to the different sinuses requires separate consideration. In general, however, it may be said that in case of acute inflammation occur- ring in any sinus active measures should be taken to subdue it, both by general measures and by such local means as shall subdue the swelling and congestion in and around the sinus-canal. Dilatation of the parts by sprays of cocaine, fol- lowed by the use of cleansing sprays, the use of steaming inhalations, and, finally, the absolute avoidance of all irritating applications, will often greatly hasten recovery. Cure may sometimes be effected in the less severe chronic conditions by removal from the points of exit of the sinus-canals of any hypertrophic tissue, polypoid growth, or other obstructive condition which may interfere with the drainage of the part. In cases not amenable to the above treatment more severe surgical measures involving forcible entrance into the sinus may be required. The interior of the frontal sinus may be approached from one of three points—namely, through its floor from just above the inner can- thus of the eye; from in front, by an incision parallel with the upper margin of the eyebrow; and from in front, by a vertical incision a little to the median line. The bony wall of the sinus may be so thinned as to be penetrated with ease. Should this not be the case, entrance may be effected by the use of the chisel or trephine. If necessary the walls of the sinus are scraped and diseased tissue, polyps, and diseased bone removed. In all cases drainage should be established from the sinus through the natural canal into the nasal cavity. To secure this Mayo Collier carries a piece of soft rubber tubing from above through the canal and out of the nose. The diameter of the tube is sufficient to completely fill the calibre of the canal, and thus prevent its walls from becoming thickened. To irrigate the wound the tube is put upon the stretch: its diameter is thereby lessened, and the antiseptic fluid is injected from the wound above downward and into the nose. The rubber tube is retained for from six to ten days, when it is removed and the outer wound closed. Others advise that the cavity be packed with antiseptic gauze and 198 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. allowed to heal from the bottom, the external wound meanwhile being kept open. Several methods are employed for treatment of suppurative disease of the maxillary sinus. These are of two varieties—namely, by entrance to it from within the nasal cavity, and from without. Where the ostium maxillare is sufficiently large and accessible, a small tube may be passed through it, and the interior of the antrum thus irrigated. In case the above conditions are not present, an artificial opening can be made through the wall of the antrum at the level of the floor of the nose. Through this systematic irrigation can be maintained. By far the most popular way, however, is to enter the sinus from without, either by withdrawing a tooth and breaking into the floor of the antrum perpendicularly through its socket, or by drilling an open- ing horizontally through the alveolar process in that part known as the canine fossa. If necessitated by the severity of the condition, a considerable section of the outer wall of the antrum may be removed and its cavity thoroughly exposed. Various devices in the way of tubes of metal or rubber are used for the purpose of keeping the opening patent, and of thus permitting the treatment to be con- tinued for an indefinite length of time. Of the various methods mentioned, entrance through the canine fossa is, on the whole, the best. Where suppurative disease of the ethmoid cells is present ob- structive thickenings must be removed, polyps destroyed, malpositions of the anterior end of the middle turbinated body relieved, or the walls of the cells entered. Preliminary to the latter operation, it may be necessary to expose the region by the actual removal of the anterior end of the middle turbinated body. This having been done by means of the Jarvis snare or a suitable cutting forceps, the anterior wall of the ethmoid cells is penetrated, and, if required, the bony septa which divide the various compartments are broken up sufficiently to allow of the free irrigation of the whole cavity. Disease of the sphenoidal sinus, the most difficult of all to reach, has sometimes been relieved by puncture of the anterior wall of the sinus and subsequent irrigation. The treatment of chronic disease of the maxillary sinus is difficult, and often exceedingly tedious operations upon the other sinuses are too serious to be entrusted to any but the most skilful hands. When it is remembered that the cavity of the sinus is separated from the orbit by an exceedingly thin plate of bone, and that its proximity to the brain is also intimate, it will be unnecessary to urge the import- ance of duly appreciating the serious character of such operations, the observance of due conservatism in resorting to them, and the employ- ment of a high grade of skill in carrying them out. It is safe to say that in no part of the body is a thorough knowledge of the anatomy of the parts more urgently necessary. Treatment of the case after the operation should consist in thorough and persistent cleansing of the parts until relief has been gained. Congenital deviations from the normal condition of the nose are sometimes found, consisting in absence or reduplication of the whole Deformities of the Nose. FRACTURE OF THE NASAL SEPTUM. 199 organ or of any of its constituent parts, in complete or partial closure of its canals, or in abnormalities of size and shape of certain of its parts. With the exception of the last-named conditions, which are common, these deformities are rare. Of the acquired deformities of the nose, deviations of the nasal sep- tum are so common as to be the rule. Practically, they are the most important abnormalities of the nose with which the surgeon has to deal. Undoubtedly the most common cause of septal deflection is trauma- tism. Some of the worst cases, however, occur in those who have been mouth-breathers from pharyngeal obstruction, and in whom the disuse of the nose on the one hand, and its altered nutrition on the other, have been active causative agents in the production of the trouble. The nasal septum is composed of three separate parts—the cartilag- inous portion, the perpendicular plate of the ethmoid, and the vomer. Any of these three parts may be fractured alone or any part of them may partake of the injury. Fracture of the septum, therefore, may be divided into three parts : first, that of the perpendicular plate of the ethmoid; second, fracture of the vomer; and third, that of the septal cartilage. Fracture of the perpendicular plate is not uncommon, occurring with fracture of the bones proper, especially where the fracture is extensive or comminuted. It may also be isolated, and in that case is likely to be found near the union of the perpendicular plate with the vomer. Fracture of the vomer is rare, and not likely to be attended with displace- ment. It is therefore difficult to recognize. Injuries to the septal carti- lage may be of the nature of dislocation or fracture. The first variety is commonly met with and often difficult to remedy. The deformity resulting from it is not confined to the interior of the nose, the tip of the organ being thrown to one side and much injury done to the facial line. The accident is common in children, and is liable to pass unrecog- nized on account of the swelling which conceals it. Actual fracture of the cartilage is more likely to happen in adult life, the cartilage in some individuals showing an early tendency to calcifica- tion, which, although not developed to an extreme degree, may be suf- ficient to render it comparatively brittle. It is due, of course, to direct violence, and this is generally associated with injury to the parts of the septum posterior to it. It is sometimes easily recognized and some- times not, owing to the fact that few septa are originally straight and by reason of the swelling which has taken place. Palpation, rhinoscopic examination—if possible, under cocaine—and the use of the nasal probe will generally give the necessary aid in recognizing injuries received within the nose. The fact that there is no external deformity of the nose may not prove that extensive injury has not been suffered within. Generally, however, the nature of the injury may be inferred by some change in its external contour, especially with regard to the tip of the nose, which will suggest the real nature of the case. The treatment is a matter always requiring a considerable amount Fracture of the Nasal Septum. 200 DISEASES AND INJURIES OF THE RESPIRATORY ORGANS. of care, skill, and judgment. In all cases great advantage is gained from an examination of the nose before swelling has taken place. Dislocation of the cartilage in children is, as a rule, impossible to remedy by any known efficient means. Complete luxation having once taken place, the base of the cartilage is so loosened that it is impossible to retain it in its normal position, and even when it is retained from the earliest period after the accident it generally happens that the displacement will recur in spite of treatment having been carried on for a long period of time. With older subjects the case is some- what easier, and even in children where complete healing of the parts has taken place considerable may be done at a period subsequent to the accident by surgical means. For the relief of these deformities Asch has attained success by incising the cartilage in the lines necessary to relieve the deformity, fracturing it at the points necessary to overcome its resiliency, replacing it in the median line, and causing the patient to wear for a number of weeks a perforated tube of hard rubber made to fit the parts. This tube may be manipulated by the patient after a little instruction, and its presence need not be irritating. This operation may be used with advantage in cases of deflection extending beyond the cartilage. Operations upon the nasal septum are commonly called for and extensively practised. They may be divided in general into two classes : 1. Those for the removal of projections in cases where the normal thickness of the septum has been increased; 2. The straightening of deflected septa whose transverse diameter has not been materially altered. These two varieties of deformity may require widely different treat- ment. Projections from the nasal septum may be removed by the use of caustics, the cautery, or electrolysis. They may require the use of some cutting instrument, such as the saw, the knife, the chisel, or the forceps. The use of caustics is mainly applicable to hypertrophy of the soft tissues of the septum, and particularly those which occur on the anterior and inferior part. The galvanic cautery is of somewhat more extensive application on account of its greater destructive power. It may be used for the destruction of cartilage and even for bone. Elec- trolysis has been used with some success for the removal of small ante- rior projections of soft tissue. For cartilaginous and osseous spurs other means will generally be required, although the electro-cautery is sometimes useful in these. Removal of these is best accomplished by some cutting instrument, the most popular of which is the simple nasal saw. The latter should be specially constructed for the purpose and of the best workmanship. The electric trephine, merely a variety of the saw, is often a valuable substitute for the latter. Variously constructed knives, scissors, and gouges are used either to separate the ridge or to reduce remaining pro- jections after the use of other instruments. The removal of septal spurs may be accomplished either with local or general anaesthesia. Where the operation promises to be severe the latter maybe required. In nearly all cases cocaine will suffice. In operating strict aseptic precautions should be attempted, notwithstanding the evident difficulty of actually securing them in the nasal passages. The patient should be seated and his head firmly sup- ported. The nasal cavity, having been cleansed and anaesthetized, should be care- fully inspected, and the exact nature, extent, and direction of the proposed incis- ion determined upon. In using the saw it is generally more convenient to cut from below upward. Everything being ready, the saw should be introduced, the line of direction carefully noted, and as little time as possible consumed in cutting through the fragment, the operation being guided by means of anterior rhinoscopy, FRACTURE OF THE NASAL SEPTUM. 201 and every precaution taken to avoid injuring the neighboring parts. The distal end of the saw should always be probe-pointed, to avoid unnecessary injury to the membrane of the posterior part of the septum and of the wall of the pharynx, which latter, however, the saw should not be allowed to touch. The bony structures hav- ing been separated, the detached fragment should be finally separated by a smooth incision through the remaining mucous membrane, made either with the knife or scissors. In using the trephine the instrument is attached to an electric motor, and is applied by the aid of rhinoscopy to the anterior end of the projection. Revolv- ing rapidly, it is caused to cut its way through the long diameter of the ridge. Where the base of the spur is narrow, its removal may be accomplished with one introduction of the trephine. If it is somewhat broad, several such attempts may be required. In cases of unusual difficulty, and where the thickness of the septum will permit, a large core may be pierced through the longitudinal centre of the projection and its final removal accomplished with the nasal saw. Irregularities remaining after the use of the trephine should be removed with the aid of some suitable instrument. Bleeding after operation is not usually severe, and in any case may be stopped by tamponing the nose with a narrow continuous strip of antiseptic gauze. The use of the tampon is often unnecessary, although, as a rule, air should be excluded from the nostril. The shock of these operations is often severe. The patient should be warned of this, and should be treated with the same consideration, as to rest and general attention, as would apply to any other surgical condition, even slight operations upon the septum being sometimes followed by considerable general disturbance. CHAPTER Y. SURGICAL DISEASES AND INJURIES OF THE FACE. Edmond Souchon, M. D. Congenital Malformations. Absence of face is called aprosopia; more or less marked imper- fections of the face are called atelo-prosopia. Congenital branchial fistuloe have been observed on the face on the line extending from the auditory meatus to the labial commissure, and also in the groove between the nose and cheek. Congenital atrophy of the face may affect the whole face or one side only. In unilateral atrophy the skin is shrunken, yellowish, hardened. In sclerema neonatorum the skin is waxy, hard, tense, cold; the body lies motionless as if the face and limbs were fixed in death; the child cannot open its mouth to suck; the disease occasion- ally appears a few days after birth. Albinism is congenital absence of pigment in the skin, hair, and eyes. Congenital hypertrophy of the face may include the whole face or only one side. Double face has been observed on a living subject. (Edema neonatorum is very rare in the face; it begins in the lower limbs and ascends. Ichthyosis is, as a rule, congenital, although the disease is seldom noticed until some little time after birth; it very rarely attacks the face. Xeroderma is the commonest form of ich- thyosis, and is often nothing more than a dry, scaly condition of the skin. The congenital “ scrofulous ” face presents three types. In the sanguine type the face is oval; the skin is thin, transparent, the veins often showing through ; the complexion oftener dark than fair; the expression is bright, sharp, and animated; the eyes are bright, and often dark; the eyelashes long, silky; the nose sharp and long, the alae contracted; the lips are thin, the teeth are white and often brittle; the lower jaw is small and angular; the hair fine and silky, often dark, not over-abundant. In the phlegmatic or melancholic type the face is round and plump; the skin is thick, pasty, muddy; the complexion is usually fair; the expression is more or less dull, heavy, apathetic; the eyes are large and full, usually pale; the nose is large, the alee thick; the nostrils open and dilated; the lips are thick, especially the upper; the teeth soon decay; the lower jaw is large and broad; the hair generally thick and coarse. In the type called pretty struma the coarseness of the features is toned down ; the lips are plump, but not tumid; the face, like the body, is plump, but not flabby (Southam). Proper and long-continued specific treatment may improve these conditions. Congenital syphilitic hypertrophy of the face in children or in young adults, presenting evidence of congenital syphilis, is characterized by prominence of the frontal eminences, imperfect development and de- pression of the bridge of the nose, opacity of the cornea, pits and scars on the face and forehead, cicatrices and fissures of the cheeks and at the 202 CONGENITAL MALFORMA TIONS. 203 angles of the mouth, malformations of the permanent teeth, especially of the central incisors of the upper jaw (Southam). Long-continued proper specific treatment will improve such appearance. Birth-marks or port-wine stains are more frequent on the face than anywhere else; they may be very small or very large; they may be level with the skin or they may be raised. They should be treated as they are in other parts—with more care, if possible, on account of the cicatricial marks. Congenital deviations of the face, or asymmetries, in which the face is thrown to one side, have been observed to a lesser or greater degree. Acquired or Post-natal Malformations of the Face.—Atrophy of the hair comprises alopecia, which is loss of hair in circumscribed, well- defined areas, with a smooth and shining skin. Pigment-atrophy is called leucoderma or vitiligo ; it presents patches of blanched skin, and is a loss of pigment in small or large areas. Although the neck is the most common situation for it, the face may also be affected. Canities is the loss of pigment of the hair-shaft. Anidrosis is absence of perspira- tion, or dry-face. Atrophy of the cuticle is usually a senile atrophy. Atrophy of the whole face or of a side or of a part of it has been observed after losses of tissue. Facial trophoneurosis, or reflex or paralytic atrophy, is the name given by Shott and Romberg to a special atrophy affecting by preference the face, where it always remains unilateral: it is due to a lesion of nutrition allied to a functional disturb- ance of the nervous system. The cause is unknown : it is not a sclerosis, but an absorption of all the tissues, especially of the connective. Hypertrichiosis or hir- suties is excessive or abnormal growth of hair, very objectionable in women espe- cially. Trichorrhexis nodosa is a nodular condition of the hair. Tinea nodosa is a nodular concretion consisting of fungus spores : it weakens the hair, which splits and breaks; it sometimes affects the hair of the whiskers, beard, or moustache. Pigment hypertrophij is called lentigo, ephilids, or freckles when it assumes the shape of a localized deposit of pigment: it is most commonly situated on the face, espe- cially about the nose and cheeks; in the pregnant female it is called chloasma ute- rinum. It is the ordinary chloasma or liver-spots when presenting a circumscribed deposit of pigment, which grows more and more diffuse so as to cover large areas. Telangeiectasis is a condition in which the capillaries are considerably dilated over a larger or smaller area of the skin : it occurs on the face and neck especially, par- ticularly in elderly people, in the form of small spots constituted by small tufts of dilated capillaries; the disease resembles the slighter form of vascular ntevus. Tinea versicolor is caused by a special fungus : it presents roundish, slightly raised, scaly patches, with well-defined borders, a peculiar brownish discoloration; it is very rare on the face. A ncevus pigmentosus or mole is a simple deposit of pigment with or without raising of the corresponding part of the skin. The bronze face of Addison’s disease, dermato-molasma, is a discoloration due to a peculiar condition of the suprarenal capsules. Xeroderma pigmentosum, or Kaposi’s disease, is a very rare affection: the initial lesions are small pigmentary spots appearing chiefly on the face, neck, and arms; they form numerous tumors which run a rapid course and end in death. Pityriasis is characterized by a brawny desquamation: it usually occupies the hairy parts; it is much more rare on the face than on the scalp. Pityriasis rubra pilaris presents at the orifice of the hair-follicles characteristic papules; on the face the lesions are often of a seborrhoeic type, a red base being covered with adherent crusts. Ichthyosis is rare on the face. A scaly-face skin is often met with in old people. Psoriasis consists of flat, dry patches of variable size covered with white, silver-gray, or asbestos-like scabs: it rarely affects the face, except in young subjects and in inveterate cases. Hyperidrosis is excessive sweating: it is sometimes limited to the course of the fifth nerve. Seborrhcea is an excessive secretion of sebaceous matter. Seborrhcea oleosa is an excess of oil-like secretion. Seborrhcea sicca is excessive secretion of sebaceous matter with excessive proliferation of unaltered epithelial cells. Seborrhcea in both forms is more com- mon on the scalp, but the eyebrows, moustache, and beard are sometimes the seat 204 SURGICAL DISEASES AND INJURIES OF THE FACE. of dry seborrhcea. On the face the oily form is more frequent, affecting especially the middle third of the face, usually the alae of the nose and naso-labial groove; also the corners of the mouth and the ears. Seborrhoea most invariably begins on the scalp ; then it spreads on the face to the eyelashes. Dermatolysis is the hyper- trophy of the integuments and subcutaneous tissues, which are all loose, pliable, feeling like fatty tissue: it is an exaggerated form of molluscum fibrosum, marked by large flaps or folds of hypertrophied skin ; their commonest site is about the neck, face, buttocks, and chest; the flaps are often deeply pigmented, thickened, indurated, and warty; hypertrophy of the bones and other subjacent tissues may also be present. Rhinoscleroma is peculiar to the nostrils and to the skin around them : it begins by nodules in the cutis, which coalesce to form a hard growth with a smooth glistening surface, which spreads inward from the lip and downward to the pharynx from the posterior nares; it is a rare affection. Sclero- derma is a diffused thickening and hardening of the skin; the skin is rigid, tense, hard like that of a frozen corpse, but without the coldness; the features are drawn and the face becomes fixed into an expressionless mask. In atrophic scleroderma the skin shrinks and becomes waxy-white in color; the face and upper limbs are the only parts attacked. Leucoderma is a similar condition, but without hardening of the integuments. Morphcea is a circumscribed scleroderma, lardaceous in appearance, mottled, with pink areoles; the lesions vary in size from half an inch to the palm of the hand ; the patches on the face sometimes follow the coui’se of the fifth pair. Morphcea is also called Addison’s keloid. The face is a favorite site for it; it presents well-defined waxy patches of a pale pink and yel- low color; it is due to some vasomotor disturbances. White keloid is a kind of scleroderma, not true keloid. The keloid of Adihert is a different disease, which develops spontaneously on cicatrices, especially on burns. Scars on the face grow with the body in the course of time. Neurotic or neuralgic hypertrophy is due to persistent neuralgia, usually affecting one side of the face only: all the tissues, even the bones, participate in it. Acute circumscribed oedema arises suddenly and subsides rapidly, only to develop in another part: its favorite seat is the face and the genitals. Frog-face is due to intranasal tumors, which, growing toward the face, raise and spread the nose and the surrounding structures. Elephantiasis \ne- sents the characteristic “ leonine face: ” it is the tubercular and mixed varieties which have a predilection for the face, nose, lips, cheeks, eyelids, chin, ears. The affected skin, especially in the nodular stage, is often the seat of seborrhoea; this gives the nodules, particularly on the face, a characteristic burnished appear- ance. The hair in the affected areas fall out. In the vast majority of cases of nodular leprosy the ends of the ears are the first parts affected. Elephantiasis Arabum is a chronic hypertrophy of the skin and subcutaneous tissues: it affects the face rarely. In the infiltrated form the face is affected after the limbs. Acromegaly affects also the face, including the soft and the bony structures. Myxoedema is a hard swelling of the face and neck and of the extremities: it is also called cachexia strumipriva, cretinoid condition, thyreopexa. It is a rare disease. Myxoedema and cretinism are totally different diseases. It is due to some destructive changes, such as fibroid degeneration, interstitial hyperplasia of the connective tissue, syphilis, atrophy of the glands; to the removal of the whole of the thyroid; in some operated cases it is due to the atrophy of that portion of the body which had been left on purpose. The anatomo-pathological lesions are hyperplasia of the connective tissue of the face and neck and extremities; the connective tissue is increased in quantity and density; there is excess of mucin in the skin and in the blood; haemoglobin is diminished; the red blood- corpuscles and the fibrin vary. The power of the red blood-corpuscles to take up oxygen may or may not be deficient. The anaemia of myxoedema is said to be due to the suppression of the hsemopoietic functions, to alteration of the regulation of the cerebral circulation, to the loss of function of the thyroid, which is an organ of depuration and elimination. The symptoms are—the skin of the face, neck, and later of the extremities, is swollen in a characteristic manner; the speech, the motions, the intellect, all the mental and bodily functions, decline; in young subjects mental development is arrested. Its course is slow; it is always progressive, without any halt or im- provement. Its duration extends usually over a year. Its termination is death. The preventive treatment consists in leaving a piece of the thyroid body in A CQ UIBED MA L FORMA TIONS. 205 all cases of total extirpation of the organ. The curative treatment consists in giv- ing thyroid extract by mouth, by hypodermic injection, or by grafting a piece of the thyroid body of an animal into some part of the patient’s* body. Acquired Deviations of the Pace.—Mutilations are on record in which one side of the face is natural, and the other drawn so as to present the expression of perpetual laughter, as depicted in Hugo’s “ L’ Homme qui Hit.” Injuries of the face would be still more frequent than they are, on account of its exposed position, but for the small size, excessive mobil- ity of the head, and the protection afforded by the arm and forearm instinctively brought up quickly in front of the face. Burns are usually deeper than they seem at first: they are often followed, in the mildest forms, by at least coarseness of features, ugly cicatrices, and deviations, whose result is dribbling of the saliva: the cicatrices sometimes interfere with the movements of the lower jaw. It is important to prevent the patient from scratching himself during sleep or delirium, so as to prevent a frequent and potent cause of increasing the deformities. Burns by acids, striking the face accident- ally or by a criminal hand, are the most frequent of the kind ; in crim- inal cases it is the face that is specially aimed at; on account of the disfigurements that follow and of the loss of the sight these burns are of the gravest character. No special treatment is here required except greater diligence. Freezing or frost-bite is common about the face on account of its exposed position. Reaction should be brought about very slowly, so as to limit the damage and leave as little cicatrix as possible. When blebs form, it is of bad omen. There often remains after recovery a purple color, for which subcutaneous injections of ergotin have been recommended. Contusions are often followed by great swelling and discoloration, especially about the eyelids (black-eye): they are specially frequent in children, who have so many falls; they affect especially the prominent parts. When the injury is located over a bone, there is formation of a lisematoma; when in soft regions, the blood becomes infiltrated. Contused and lacerated wounds often present a lesion of the deep much greater than of the superficial parts, as it is the underlying bone that has done the cutting. Contused wounds produced from without are the most frequent; sometimes they are very extensive, such as a result of the kick of a horse, terrific falls, etc., and large portions of the facial mask are torn away and hang down. Deep sutures can be placed to advantage to support and approximate the parts. Punctured wounds, when deep, are apt to be followed by subcu- taneous hemorrhage: they may penetrate one of the cavities, where the weapon may be broken, as in the maxillary sinus, orbit, cranium. Incised wounds usually gape much : very often fatty lobules pro- trude between the edges of the wound. Sabre wounds sometimes carry away the whole of projecting parts ; they bleed freely. Great care should be taken to approximate the edges properly, so as to avoid unsightly cicatrices : fine needles should be used, also fine silk; plaster strips or collodion should be placed over them. These wounds unite generally 206 SURGICAL DISEASES ANI) INJURIES OF THE FACE. by first intention, because the skin, subcutaneous tissue, and muscles form but a single matted layer or structure. Gunpowder dams should be removed at once and thoroughly : if they are allowed to remain, they will remain for life. If necessary, cocaine or an anaesthetic must be used; the parts should be first scrubbed with a hard nail-brush ; then all the grains of powder must be picked out, one by one, employing a cataract needle; a 1 per cent, solution of mercuric chloride will facilitate the removal of the grains of powder. Gunshot wounds of the soft parts of the face alone are very rare. There exists a case on record of perforation of both cheeks by a bullet without injury to the bones or teeth in an officer who was wounded when uttering an enthusiastic hurrah. Gunshot wounds from a distance are the rule in war, and may be terrific: in one case the whole face was destroyed except the eyes, and the patient survived, feeding through a tube which he introduced in the oesophagus. Gunshot wounds at close range are most commonly due to suicidal efforts. Such wounds may be complicated by the lodgement of a ball or other foreign body in any one of the cavities of the face; by the lesion of some organ or nerve of special sense; by fracture of the base of the skull; by injury to sali- vary glands, teeth, lachrymal glands. Besides, the softness of the bones allows the missiles to penetrate deeply and the tissues to contract over them ; hence arises great difficulty in removing them. Arrow wounds produce great bleeding; all the above remarks concerning gun- shot wounds are applicable to them. The immediate complications of the wounds of the face are emphysema, due to fracture of nasal fossae or maxillary sinuses; wounds of Stenson’s duct; cerebral contusion : this is not very frequent nor severe; it is, on the contrary, remarkable how few cerebral symptoms develop after violent injuries of the face; this is due to the fact that the bones are soft and yield readily. Wounds of the deep arteries give rise to hemorrhage through the mouth, without our being able to ascertain positively whence the blood comes. The secondary complications are oedema of tongue and pharynx, interfering with deglutition, cephalic tetanus, persistent neur- algias, cramps, and contractures. Secondary hemorrhages are frequent in lacerated and gunshot wounds of the face ; they usually take place between the fifth and the twenty-fifth day: it is the small deep vessels that are the troublesome factors. No styptics should be used, especially here: it is preferable to use methodical plugging with long narrow strips that are well packed in small segments in all the nooks and corners with as hard a compression bandage as the patient can stand. The bleeding arteries should be ligated in situ if possible, but this is very difficult, and often unsatis- factory on account of the inflamed and sloughing condition of the tissues. By applying a provisional loop ligature around the common carotid the hemorrhage- may be controlled until a thorough search and a satisfactory ligature of the bleed- ing points be accomplished in situ, when the provisional ligature is removed. In such cases the common carotid should be exposed close to its bifurcation, so that if the above procedure should fail, the external carotid is within easy reach. It might be well borne in mind that it is the external carotid that must then be ligated, not the common carotid, on account of possible cerebral complications. In extensive or general bleeding it may be necessary to ligate both external carotids: in such an emergency the ligations should be applied above the origin of the linguals. The sequels of injuries of the face are reflex contractions of the muscle of the face from a wound of the face or scalp, constrictions of the jaws, ectropion of the lids or lips, atresia of the mouth. These injuries are sometimes followed by amaurosis, especially if they occur near the orbit or the malar bone; the lesion is often a dislocation of the lens or a detachment of the retina; sometimes there is no detectable lesion. NEUROSES OF THE FACE. 207 Mortality of injuries of the face is comparatively low, because the vessels and the bones are small, the bones are thin, the parts naturally drain well through the nose and mouth, and the vascularity and the nutritive powers are here at their best. During the War of Secession 90 per cent, recovered, some with horrible mutilations. Fractures of the nose are treated elsewhere. (Vide Vol. I.) Poisoned wounds, stings of bisects, of spiders, etc. are common, be- cause of the exposed condition of the face ; the swelling spreads rapidly and is particularly disfiguring. In cases of bites of horses or of dogs there is a flap corresponding to the upper jaw of the animal and one of the lower jaw. Bites of rabid animals are much more rapidly followed by hydrophobia, because the distance to the brain is so much shorter than when the hand or any other part is the site of the injury; also because, the teeth penetrating at once into the tissues without passing through any clothing, the inoculation is more thorough and more viru- lent. All poisoned wounds of the face should be treated as in other regions. Neuroses of the Pace.—Anaesthesia of the skin of the face is usually due to the paralysis of the trifacial; it is a symptom of a lesion of the nerve-centres. Double paralysis of the face is called diplegia. Facial paralysis, or Bell’s palsy, is usually caused by brain lesions, but may be due to the effects of cold on the nerve, of blows, of wounds or operations injuring the nerve in some point of its course or at its point of emer- gence ; diseases of the temporal bones (fractures or caries), or otorrhoea. Its peculiar symptoms are inability to close the eye, prolapse of the cheek, eversion of the lower lip, the deviation of the face toward the sound side. When the patient laughs, the expression of the whole face is most peculiar and characteristic. The treatment varies with the cause. Facial hyper- cesthesia comprises dermatalgia, or painful skin, or pruritus or itching, especially of the skin of the beard or of the nares; it is rather rare. Facial neuralgia is called tic douloureux when the pain is accompanied by contraction of the muscles; its special cause here is often a carious tooth, although the tooth itself may be painless; the other causes are painful cicatrices, foreign bodies, callus including a nerve, tumors, inflammations, diseases of the petrous bone or intracranial tumors. Its special treatment in obstinate cases is the stretching or the section of the nerves at their points of emergence (neurotomy and neurectomy) or the removal of the Gasserian ganglion. Facial spasm, or convulsive tic with- out pain, is a clonic spasm causing contortions of the side of the face: it ceases during sleep. Cephalic hydrophobic tetanus may result from a bite of a non-rabid animal; it affects the course of a cranial nerve; the facial nerve is paralyzed on the side of the wound. The symptoms are those of hydrophobia; the face is congested and haggard. Chromidrosis and purpura are mentioned here for want of a better place. Chro- midrosis is a colored secretion of the sweat and sebaceous fluids, usually blue in color, or red, yellow, green, or violet: it is usually symmetrical; its favorite site is the eyelids, next the cheeks, the forehead, the sides of the nose, sometimes the whole face and the body. Purpura is the extravasation of blood in the cutis; it is rare in the face compared with the other parts of the body; it is there most commonly situated in the eyelids. The treatment must be general and directed to the blood. Furuncles or boils most frequently affect the face and neck. Car- 208 SURGICAL DISEASES AND INJURIES OF THE FACE. buncles of the face are comparatively rare and nearly always fatal. These lesions are particularly grave about the face, because of the septic absorption by the facial vein and its direct conveyance to the sinuses of the brain. Carbuncles should be freely incised or curetted at the very outset. Erysipelas is common : it is usually due to some lesion in the interior cavities, buccal, nasal, pharyngeal, Eustachian tube or external auditory canal; it emerges from the tip of the nose or from the lachrymal points or from the external auditory canal. When it first travels through the Eustachian tube and the middle ear it is preceded for two or three days by most agonizing pains: it is more serious here than anywhere else, because of the propaga- tion to the brain and membranes. It seldom stops until it has gone over the whole face and head, seldom extending beyond the neck to the trunk: it usually leaves the features coarser than before its advent. Of course the interior cause must receive proper attention dur- ing the attack, and also afterward in order to prevent a return: it requires here no particular treatment. Erysipelas of the face is some- times complicated with pericarditis, myocarditis, and oftener with endo- carditis (Gubler). Malignant pustule is also comparatively frequent, for the reason of easy access to the face: it is more fatal here because the radical means of treatment are not so easily applied as on the hands; also because of the close proximity of the brain and its sinuses. Glanders shows externally first by an inflamed and ulcerated con- dition of the nostrils and upper lip. Cellulitis is rare, because of the adhesion of the skin to the muscles and of these to the bones. Congestions of the face do not spread easily for the same reasons. But septic inflammations are often followed by much swelling, oedema, and hardness. They should be treated as in other regions. Cellulitis and abscesses of face are usually due to diseased teeth or to osteoperiostitis of the jaws. Abscesses are also comparatively rare: most frequently they originate from the root of a decayed tooth. Abscesses of the face should be incised with the greatest care, bearing in mind the direction of the folds or wrinkles of the vessels, the nerves, Stenson’s duct,—all this on account of the scar that may follow; for these reasons it is often best when circumstances permit to let them open for themselves, when the scar is reduced to a small round white spot less noticeable than a cut. Phlebitis of the facial vein is rarely primary: it usually follows other inflammations of the face, especially furuncles and carbuncles, and particularly those of the upper lip. It is characterized by rapid swelling, with oedema, intense pain, sen- sation of strangulation; the face is earthy pale, the course of the veins marked by blue lines. Gangrene of the Face.— Gangrene of the face is rarely primary : it is usually due to injuries, to carbuncles, to malignant pustules. Can- crum oris, or noma, is peculiar to the cheeks. Great care is neces- sary to limit the following deformity as much as possible. Raynaud’s disease is symmetrical gangrene of the extremities, including in this term the tip of the nose and the ears: the order of frequency is the fingers, toes, heels, nose, ears. Ulcers of the face may be due to many causes. Tubercular ulcers are the most frequent outside of syphilis ; they are called lupus, and the face is their favorite site. Lupus erythematosus is not tubercular. Lupus non-exedens is characterized by an eruption of pale or reddish tubercles which ulcerate, become covered with white scales and scabs, which on coming away leave behind a smooth white depressed cicatrix. Lupus exedens destroys by ulceration; lupus non-exedens destroys by atrophy. FORMS OF ULCER OF THE FACE. 209 The favorite site of lupus is the face. Lupus vulgaris, or malignant herpes, is also a form of tubercle of the skin due to the bacillus: it appears as small tumors on the skin, especially on the forehead, cheeks, and nose; the lesions are grouped tubercles of apple-jelly color and consistency, smooth, tending to ulceration. It is more grave; it resembles epithelioma, but is less painful; the edges are not as hard and elevated ; the favorite site of lupus is the face, especially the nose and the neigh- boring part of the cheeks. Nodular lupus presents more or less localized nodules, tubercles, and nests, reddish or yellowish pink; often quasi-gelatinous; it usually attacks the cheeks near the junction of the alse and the upper lip. Diffused lupus is superficial, less inclined to form nodules and nests: affects the cheeks and nose most frequently. Lupus seborrhceicus (Volkmann) presents irregular nodular patches on the cheeks and nose, covered with dirty-looking skin, crusts fatty to the touch: after partially scraping off the scab the underlying skin appears red, sore, as if studded with fine warts; but when examined with a lens are seen a number of fine holes, which are the enlarged openings of the sebaceous ducts: each single fatty crust has a fine prolongation of the latter, which becomes detached from each opening. Ulcers of the face which resist ordinary treatment should be cocain- ized and curetted; if necessary they should be extirpated like cancers. The Biskra button or Aleppo boil is a tropical disease beginning by a boil which leaves a foul ulcer : it is due to a micro-organism. Syphilitic ulcers are common in all their forms and varieties—papular, tubercular, rupial, etc. General specific treatment is indispensable. Indurated chancres may occupy any part, but they are more rare than around the mouth; they are sometimes two or three in number; they are usually accompanied by a hard and purple oedema, with greater nodular engorgement than in other situations. Chancroids or soft chancres of the face have been observed, but are very rare. Tertiary syphilitic ulcers are tuberciilo-ulcers and resemble lupus : they often pre- sent here a rapid evolution, and are rebellious to specific treatment, destroying soft parts and bones alike, followed by destruction of nose, and cicatrices, causing atresia and ectropion of the natural orifices. Yaws, or framboesia, presents reddish papules, tubercles, or tumors studded with yellow points, which ulcerate: it is a very rare disease. It may appear first on the lip; sometimes the papules are arranged in rings, especially round the eye, nose, mouth, and the genitals. Tertiary ulcers of yaws are also common about the lips. Cancerous ulcers are limited usually to the skin ; however, cancers on the deeper tissues, and especially the bones, finally ulcerate. Cancers commencing on the skin are the squamous epithelioma and the rodent ulcer. Rodent ulcer is a form of epithelioma: it is remarkable that almost every case of rodent ulcer has its seat within an area bounded by a line drawn from the uppermost point of the pinna to the root of the nose, and another drawn from the lobule of the ear to the columella of the nose. It exceptionally occurs on the hands. It must be thoroughly curetted or destroyed by pastes or extirpated. (Vide Vol. I. p. 429, Figs. 177, 178.) Epithelioma is the most common of all cancerous affections of the face, which is a favorite site for it. It is important to remember its forms and varieties—superficial or flat epithelioma, presenting scales or a grouping of papules or an inflamed sebaceous outlet; the indurated or circumscribed; the papillary; the infiltrated or diffused, which resembles the condition of chronic inflammation : sometimes it begins by separate spots which coalesce; there is no elevation of the diseased 210 SURGICAL DISEASES AND INJURIES OF THE FACE. parts. Epithelioma of the face when small should be curetted or attacked with pastes, but when of size or deep, extirpation is the best remedy : early interference is most desirable to avoid large scars. In operating, grafting and plastic operations must be resorted to to reduce the cicatrices and deformities to a minimum. The lymphatic nodes receiving the lymphatics from the infected parts should be removed if in the least indurated: because of the neglect of this it is common for the disease to show on the parotid region or the submaxillary, requiring there much more dangerous and extensive operations for the eradication of the disease. Fistulse of the Face.—Fistulse of the face are not very common: they may be congenital—e.
